How to read files in python?

First, create a txt document on the desktop and enter the following content:

你好。
Hello.
abcdefg
啊不错的风格

Recommendation: "Python Tutorial》

View the properties of the file and get the absolute path of the file:

D:\HintSoft\Hint-W7\Desktop

##The file name is——New text document.txt,

Then, the absolute path plus the file name is the absolute file name:

D:\HintSoft\Hint-W7\Desktop\新建文本文档.txt

Open this file with python and name it f.

f = open(r"D:\HintSoft\Hint-W7\Desktop\新建文本文档.txt",'r')

There is no output above, because after opening the file, the content has not been read:

f = open(r"D:\HintSoft\Hint-W7\Desktop\新建文本文档.txt",'r')
s=f.read()
print(s)

In this way, python returns all the information in the file .

What if we only want to read the first 6 characters?

f = open(r"D:\HintSoft\Hint-W7\Desktop\新建文本文档.txt",'r')
s=f.read(6)
print(s)

In this way, only the first 6 characters will be returned.
