如何在列表中的字符串中找到单词?(Python) [英] How to find a word in a string in a list? (Python)

问题描述

因此，我正在尝试寻找一种方法，以便我可以读取txt文件并找到特定的单词.我一直使用

So im trying to find a way so I can read a txt file and find a specific word. I have been calling the file with

myfile=open('daily.txt','r')

r=myfile.readlines()

这将返回一个列表，其中包含文件中每一行的字符串，我想在列表中的字符串之一中找到一个单词.

that would return a list with a string for each line in the file, i want to find a word in one of the strings inside the list.

对不起，我的意思是，如果有一种方法可以找到该单词在txt文件中的位置，例如 x = myfile [12] x = x [2:6]

edit: Im sorry I meant if there was a way to find where the word is in the txt file, like x=myfile[12] x=x[2:6]

推荐答案

def findLines():
    myWord = 'someWordIWantToSearchFor'
    answer = []
    with open('daily.txt') as myfile:
        lines = myfile.readlines()
    for line in lines:
        if myWord in line:
            answer.append(line)
    return answer
