在文本中的单词巧合

Question

嗨，大家好，我想算一个单词和他的收缩次数（就像你和你一样）。问题是我没有找到方法来解决我的收缩问题。

您可能希望将文件拆分为撇号，空格以及任何其他标点符号。要在多个分隔符处拆分，您需要import re并使用正则表达式。

如果您还希望匹配不同案例的字词（例如“您和您”），则需要使用lower()。

import re  # use regular expressions

def paraula(file,palabrabuscar):
    abrirLetra = open(file) #Open the file
    palabras = ""
    vegades = 0
    for palabras in re.split(r'[\s\'\"\.,;]+', abrirLetra.read()):
        # split at every: \s whitespace
        #                 \' apostrophe
        #                 \" quotation mark
        #                 \. full stop
        #                  , comma
        #                  ; semi-colon
        #
        # The plus sign at the end splits at one or more delimiters in
        # a row (for example "Hello. Hi." has a full stop and a space 
        # together between Hello and Hi).
        #
        # Backslashes are added before special characters
        # (for example s matches the letter s, but \s matches whitespace).

        if (palabras.lower() == palabrabuscar.lower()): #Look for coincidence
            # Convert both to lowercase if you want to match
            # you, You and YOU.
            vegades = vegades +1

    abrirLetra.close()
    return vegades

file = 'lletra.txt'
print paraula(file,"you")
