re.findall(r'[a-zA-Z]+(\'[a-zA-Z]+|\b)',string)

##Warning##

There are some mistake use this re in Python. It works well in Sublime. I will try to fix it in several days. Thank you!

import re

def list1(string):

words = re.findall(r'[a-zA-Z]+\b',string) #修改了正则表达式

return words

def file_read(filename):

with open(filename,'r') as fp:

article = fp.read()

return article

def most_word_number(word_list):

str_dict = {}

for item in word_list:

if item in str_dict:

str_dict[item] +=1

else:

str_dict[item] =1

str_dict = {str_dict[key]:key for key in str_dict}

return (max(str_dict),str_dict[max(str_dict)])

if __name__ == '__main__':

string = file_read('GitHub.txt')

words = list1(string)

print (most_word_number(words))

GitHub

From Wikipedia, the free encyclopedia

GitHub is a web-based Git repository hosting service, which offers all of the distributed revision control and source code management (SCM) functionality of Git as well as adding its own features. Unlike Git, which is strictly a command-line tool, GitHub provides a web-based graphical interface and desktop as well as mobile integration. It also provides access control and several collaboration features such as wikis, task management, and bug tracking and feature requests for every project.[2]

GitHub offers both paid plans for private repositories and free accounts, which are usually used to host open-source software projects. As of 2014, GitHub reports having over 3.4 million users and with 16.7 million repositories[3] making it the largest code host in the world.[4]
