Sometimes it is necessary to specify space on a line, but the amount of free space is uncertain and depends on the environment and conditions. In these cases, changing the line over and over again is a tedious task. Hence, python has a " expandtabs () " in its library, which determines the amount of space that should be replaced with "/ t" in a line.

Syntax: expandtabs (space_size)

Parameters:
space_size: Specifies the space that is to be replaced with the “ ”Symbol in the string. By default the space is 8.

Returns: Returns the modified string with tabs replaced by the space.

Code # 1: Code for demo extended tables ()

# Python3 demo code
# working with extensions ()

# initializing string

str = "i love gfg"

# using the space insertion extension

print ( "Modified string using default spacing:" , end = "")

print ( str . expandtabs ())

print ( "" )

# using an extension to insert spaces

print ( "Modified string using less spacing:" , end = "")

print ( str . expandtabs ( 2 ))

print ( "" )

   
  # using a space insertion extension  
   print   (  "Modified string using more spacing:"  , end   =   "") 
   print   (  str  . expandtabs (  12  )) 
   
   print   ( " " )

Output:

 Modified string using default spacing: i love gfg Modified string using less spacing: i love gfg Modifi ed string using more spacing: i love gfg

Exception:
The exception with this method is that it does not accept a floating point number if we want to determine the exact precision of the space required.

Code # 2: Code to demonstrate exclusion from extended tables ()

       # Python3 demo code  
  # extended tables exception ()  
    
  # initialization string  
   st   =  " i love gfg " 
    
  # use the space insertion extension  
   try  : 
   print   (  "Modified string using default spacing:"  ) 
   print   (st.expandtabs (  10.5  )) 
   
   except   Exception as e: 
   print   (  "Error !! The error occurred is: " ) 
     print   (  str   (e))

Output:

 Modified string using default spacing: Error !! The error occurred is: integer argument expected, got float

Applications:
There are many possible applications where this can be used, such as text formatting or documentation where user requirements are constantly changing.
