Python Operations on files

1. Reading files

The file is Read_it.txt and the contents are:

1) read files by character

#按字符读取文件text_file =open ("Read_it.txt", "R") print (Text_file.read (1)) Print (Text_file.read (5)) Text_file.close ()

The output result is

Read () can read a specified number of characters from a file, and the resulting result is returned as a string. Each time read () starts at the last place where it ended.

#按字符读取文件text_file =open ("Read_it.txt", "R") Whole_thing=text_file.read () print (whole_thing) text_file.close ()

The output result is

If you do not specify the number of characters, Python returns the entire file as a string.
