Python | Ways to split strings on Uppercase characters
  • Last Updated : 20 Aug, 2020

Given a string, write a Python program to split strings on Uppercase characters. Let’s discuss a few methods to solve the problem.
Method #1: Using re.findall() method

import re
 
# Initialising string
ini_str = 'GeeksForGeeks'
 
# Printing Initial string
print ("Initial String", ini_str)
 
# Splitting on UpperCase using re
res_list = []
res_list = re.findall('[A-Z][^A-Z]*', ini_str)
 
# Printing result
print("Resultant prefix", str(res_list))

Output: 

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

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

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)]
 
# Printing result
print("Resultant prefix", str(res_list))

Output: 

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