The use of the Join () function in Python

Function: String.Join ()

Python has join () and Os.path.join () two functions, which work as follows:
Join (): An array of connection strings. Generates a new string from a string, tuple, or element in the list, with the specified character (delimiter) connection
Os.path.join (): Combine multiple paths to return

First, function description
1. Join () function

Syntax: ' Sep '. Join (SEQ)

Parameter description
Sep: Delimiter. Can be empty
SEQ: sequence of elements to concatenate, strings, tuples, dictionaries
The syntax above is to combine all the SEQ elements into a new string with Sep as a delimiter

Return value: Returns a string that is generated after each element is concatenated with the delimiter Sep

2. Os.path.join () function

Syntax: Os.path.join (path1[,path2[,......])

Return value: Combine multiple paths to return

Note: Parameters before the first absolute path are ignored
