"如何将文本文件作为字符串读取？"

Question

Below are the codes I have tried to read the text in the text file in a method called check_keyword()

def check_keyword():
    with open(unknown.txt, "r") as text_file:
        unknown = text_file.readlines()

    return unknown

This is how i called the method:

dataanalysis.category_analysis.check_keyword()

The text in the text file:

Hello this is a new text file 

There is no output for the method above :((

Answer 1

text_file.readlines() returns a list of strings containing the lines in the file. If you want only a string, not a list of the lines, use text_file.read() instead.

You also have another problem in your code, you are trying to open unknown.txt , but you should be trying to open 'unknown.txt' (a string with the file name).

Answer 2

You can do this as follows:

with open("foo","r") as f:
    string = f.read()

Answer 3

而不是text_file.readlines()使用text_file.read()它将以字符串格式而不是列表为您提供文件内容。

Answer 4

The code is just a working code based on all the above answers.

def check_keyword():
    with open("unknown.txt", "r") as text_file:
         unknown = text_file.read()

     return unknown

check_keyword()

Answer 5

Actually i have made a whole lib to make that work easy for all

from filemod import reader
data=reader("file.txt))
print(data)
