如何讀取一行並忽略一些單詞（python）

Question

我正在逐行讀取文本文件，我想忽略所有出現的“和”，“收件人”和“發件人”並返回其余部分。 python中有一個函數可以讓我這樣做嗎？ 謝謝你的幫助。

使用替換或拆分空格中的線並重新組裝而不使用您不需要的單詞，例如：

In [6]: testsrt = 'I\'m reading a text file line by line and i want to ignore all occurrences of and , To and From and return the rest. Is there a function in python that will allow me to do that? Thanks for your help.'

In [7]: ts = testsrt.split(' ')                                                                                                                                                                                                                   

In [8]: excl = ["and", "To", "From"]                                                                                                                                                                                                              

In [9]: ' '.join([t for t in ts if not t in excl])                                                                                                                                                                                                
Out[9]: "I'm reading a text file line by line i want to ignore all occurrences of , return the rest. Is there a function in python that will allow me to do that? Thanks for your help."                                                          

請注意，如果您保留引號，則不會刪除單詞，因為這是逐字工作的。

您還可以將re.replace視為一種繼續進行的方式。
