Method # 1: Using the re.findall () method

# Python code for demonstration
# split lines
# capital letter

import re

# Initialization string

ini_str = ’GeeksForGeeks’

# Print start line

print ( "Initial String" , ini_str)

# UpperCase split using re

res_list = []

res_list = re.findall ( ’[AZ] [^ AZ] *’ , ini_str)

# Print result

print ( "Resultant prefix" , str (res_list))

Exit:

 Initial String GeeksForGeeks Resultant prefix [’Geeks’,’ For’, ’Geeks’]

Method # 2: Using re.split ()

# Python code for demo
# split lines
# capital letter

import re

# Initializing string

ini_str = ’GeeksForGeeks’

# Print start line

print ( "Initial String" , ini_str)

# UpperCase split using re

res_list = [s for s in re.split ( "([AZ] [^ AZ] *)" , ini_str) if s]

# Print result

print ( " Resultant prefix " , str (res_list))

Exit:

 Initial String GeeksForGeeks Resultant prefix [’Geeks ’,’ For’, ’Geeks’]

Method # 3: Using enumeration

       # Code Python for demonstration  
  # split lines    # capital letter  
   
  # Initializing string  
   ini_str   =   ’GeeksForGeeks ’ 
    
  # Print start line  
   print   (  "Initial String"  , ini_str) 
    
  # UpperCase split using re  
   res_pos   =   [i   for   i, e   in   enumerate   (ini_str   +   ’A’  )   if   e.isupper ()]  
   res_list   =   [ini_str [res_pos [j]: res_pos [j   +   1  ]] 
   for   j   in   range   (  len   (res_pos )   -   1  )]  
   
  # Print result  
   print   (  "Resultant prefix"  ,   str   (res_list))

Exit:

 Initial String GeeksForGeeks Resultant prefix [’Geeks’,’ For’, ’Geeks’]
