Find all capital letters word - Word и Excel - помощь в работе с программами

I’m writing out a small snippet that grabs all letters that start with a capital letter in python . Here’s my code

def WordSplitter(n):
    list1=[]
    words=n.split()
    print words

    #print all([word[0].isupper() for word in words])
    if ([word[0].isupper() for word in words]):
        list1.append(word)
    print list1

WordSplitter("Hello How Are You")

Now when I run the above code. Im expecting that list will contain all the elements, from the string , since all of the words in it start with a capital letter.
But here’s my output:

@ubuntu:~/py-scripts$ python wordsplit.py 
['Hello', 'How', 'Are', 'You']
['You']# Im expecting this list to contain all words that start with a capital letter

You’re only evaluating it once, so you get a list of True and it only appends the last item.

print [word for word in words if word[0].isupper() ]

for word in words:
    if word[0].isupper():
        list1.append(word)

You can take advantage of the filter function:

l = ['How', 'are', 'You']
print filter(str.istitle, l)

I have written the following python snippet to store the capital letter starting words into a dictionary as key and no of its appearances as a value in this dictionary against the key.

#!/usr/bin/env python
import sys
import re
hash = {} # initialize an empty dictinonary
for line in sys.stdin.readlines():
    for word in line.strip().split(): # removing newline char at the end of the line
        x = re.search(r"[A-Z]S+", word)
        if x:
        #if word[0].isupper():
            if word in hash:
                hash[word] += 1
            else:
                hash[word] = 1
for word, cnt in hash.iteritems(): # iterating over the dictionary items
    sys.stdout.write("%d %sn" % (cnt, word))

In the above code, I shown both ways, the array index to check for the uppercase start letter and by using the regular expression. Anymore improvement suggestion for the above code for performance or for simplicity is welcome

In this post, we will learn how to extract uppercase words in string Python with examples. We have used Regular expression to extract capital words from a given string.” A regular expression (or RE) specifies a set of strings that matches it; the functions in this module let you check if a particular string matches a given regular expression”.We will cover extracting uppercase words from lists in Python, extracting alphanumeric uppercase words from strings in Python, Extract Only uppercase letters from strings in Python, Count uppercase letters from strings in Python

In this example, we have extracted all uppercase words from Python string using Regular expression. In such a case first, we have to import the Regular expression module in our program using “import re”.The regular expression is as follows. The re module findall() function will return the word that matches the given pattern.

[A-Z]: It extracts capital letters between A-Z.
b: Start of word

import re
strText = 'Welcome to DEVENUM.COM,LET FIND UPPER CASE STRING';
print(re.findall(r'b[A-Z]+(?:s+[A-Z]+)*b', strText))

Output

['DEVENUM', 'COM', 'LET FIND UPPER CASE STRING']

2. How to extract uppercase words in string Python using Regex

In this example, We are using the Regular expression ‘[A-Z]+’ to extract the uppercase letter and upper words from a string. Let us understand code and output.

import re
myStr = "Welcome folks'S TO DEVENUM! HOW ARE YOU"
pattern =  '[A-Z]+'
print(re.findall(pattern, myStr))

Output

[' TO DEVENUM', ' HOW ARE YOU']

3. Extract uppercase words from list in Python

To extract uppercase words from a list in Python. We have iterated over the list using for loop and on each iteration, we have extracted uppercase words using the Regular expression using the re.findall() function and display the result.

import re
mylist = ['Welcome','to','DEVENUM','COM','LET', 'FIND','CASE']
for item in mylist: 
 print(re.findall(r'b[A-Z]+(?:s+[A-Z]+)*b', item))

Output

[]
[]
['DEVENUM']
['COM']
['LET']
['FIND']
['CASE']

4. Extract uppercase alphanumeric words of string in Python

We have used alphanumeric words from a string.We have used Regular expression [A-Z0-9][A-Z0-9]+|b[A-Z] where 0-9 used to include digit while matching the string.

import re
myStr = "Welcome D2'S TO D56EV ENUM! H69OW A89E Y20OU"
pattern =  '[A-Z0-9][A-Z0-9]+|b[A-Z]*b'
print(re.findall(pattern, myStr))

Output

['D2', 'TO', 'D56EV', 'ENUM', 'H69OW', 'A89E', 'Y20OU']

5. Extract Only uppercase letters from string Python

To find all the upper case letters from a string. We have used the filter function along with lambda and checked if the character in a string is uppercase using isupper() method. To return a list we have converted the result to a list using the list() method.

strText = 'Welcome to DEVENUM.COM';


def Is_upper_Letter(myStr):
    return list(filter(lambda char: char.isupper(), myStr))

print(Is_upper_Letter(strText))

Output

['W', 'D', 'E', 'V', 'E', 'N', 'U', 'M', 'C', 'O', 'M']

6. Count uppercase letters in string Python

To find the count of uppercase letters in a given string. We have iterated over each character of the string by using generator expression. When the upper case character is found, return the character to the sum function and when iteration is over, the sum function will return the count of all upper case letters in the string.

strText = 'Welcome to DEVENUM.COM';
UpperCase_count = sum(1 for item in strText if item.isupper())
print('Upper case letter in String :',UpperCase_count)

Output

Upper case letter in String :11

Summary

In this post, we have learned How to extract uppercase words in string Python by using regular expressions and findall() function of the re module. We have also covered, extracting uppercase words from lists in Python, extracting alphanumeric uppercase words from strings in Python, Extract Only uppercase letters from strings in Python, Count uppercase letters from strings in Python

Someone in one of my online editing groups wanted to find all the acronyms and initialisms in their document—any word comprising two or more capital (‘cap’) letters (e.g. AB, CDEF, GHIJK, etc.). They wanted a command that would find each one so they could check it (possibly against a glossary), then click Find Next to jump to the next one.

Wildcards to the rescue!

Here’s how:

Press Ctrl+H to open the Find and Replace window.
Click the Find tab (we only want to find these, not replace them with anything else).
Click More to show further options.
Select the Use wildcards checkbox.
In the Find what field, type: <[A-Z]{2,}>
Click Find next to find the first string of two or more caps.
Keep clicking Find next to jump to the next string of two or more caps.

How this works:

The opening and closing arrow brackets (< and >) specify that you want a single whole word, not parts of a word. Without these, you would find each set of caps (e.g. in the string ABCDEF, you would find ABCDEF, then BCDEF, then CDEF, then DEF, then EF, before moving on to the next set of caps).
[A-Z] specifies that you want a range (the [ ] part) of caps that fall somewhere in the alphabet (A-Z). If you only wanted capped words that started with, say, H through to M, then you’d change the range to [H-M] and all other capped words starting with other letters would be ignored.
{2,} means you want to find capped words with at least two letters in the specified range (i.e. A-Z). If you only wanted to find two- and three-letter capped words, then you’d change this to {2,3}, and all capped word of four or more letters would be ignored. By not specifying a number after the comma, the ‘find’ will find capped words of any length containing at least two letters.

Finding capital letters in Word

(OP)

12 Sep 07 14:13

Hi,
I often have to define acronyms and abbreviations in words, which are mainly capitalised, so it would be really useful to be able to do a Find on capital letters in Word (2003). In the Find box, I notice that you can find such things as ‘any letter’ or ‘any digit’, and that some have codes (such as ^$ for any letter), but I can’t see anything for capital letters. Is there a way of doing this, such as a code?
Many thanks,
Sam
