The common data file types in Python are text files, binary files and CSV files.

The text file is encoded by ASCII, and the man stores the internal code.

Binaries are files encoded with variable length based on values, which cannot be viewed directly by a text compiler.

Comma separated value (csv) files, preferably with a text compiler

2 File object

The backslash in a string is an escape character, so you can represent the path of a string in two special ways.

Precede the string with r

Hierarchical relationships in path strings are represented by double backslashes

Os.getcwd: returns the current work path as a string

Os.chdir (path): modifies the current work path to the work path specified by path

Os.listdir (path): get all the files and folders under the work path specified by path

Common properties of file objects:

Name: indicates the file name that contains the path

Close: indicates the status of the file. Turn it off to True and open to False.

Mode: indicates the file open mode

File object open mode:

R: indicates read-only mode

W: indicates write-only mode

A: indicates the append mode

B: represents binary mode and can be combined with (can be used in combination with r, w, a modes)

T: indicates the text mode, which can be omitted

+: indicates read-write mode
