Python 3.6将文本输出为.txt文件

Question

Basically I want my python code to be able to read the line I have in my .txt file and print it out in another file when called.

What I have tried:

var = open("Test.txt")
print(var)

I have also tried using readlines():

var = open("Test.txt")
abcd = var.readlines()
print(abcd)

And what I get when I use that:

<_io.TextIOWrapper name='Test.txt' mode='r' encoding='US-ASCII'>

Answer 1

What you are printing is only the object reference of the file and not the actual text within it. When printing out the content of a file in python you must use the read() function to return the content of the file. You should also specify the actions you want to take with the file in the open() function.

• r is read
• w is write
• r+ is read and write

For your situation you would use:

    var = open('Test.txt', 'r')
    content = var.read()
    print(content) 

This would return the entire content of the file.

Answer 2

Start with a context manager, what does this get you?

with open('Test.txt', 'r') as f:
    content = f.read()

print (content)
