*Memo for string, bytes and bytearray functions:

*Memo for a string, bytes and bytearray:

str.expandtabs() and bytes.expandtabs() or bytearray.expandtabs() can replace \t of the string and bytes or bytearray with zero or more spaces respectively as shown below:

*Memo:

  • The 1st argument is tabsize(Optional-Default:8-Type:int):
    • It's the tab size to replace \t with zero or more spaces.
    • The number of spaces depends on the word before \t.
