Given a String, perform uppercase of later part of string.
Input : test_str = ‘geeksforgeek’
Output : geeksfORGEEK
Explanation : Latter half of string is uppercased.Input : test_str = ‘apples’
Output : appLES
Explanation : Latter half of string is uppercased.
Method #1 : Using upper() + loop + len()
In this, we compute the half index, and then perform upper() to only those characters which lie in other half of string.
Python3
# Python3 code to demonstrate working of # Uppercase Half String # Using upper() + loop + len() # initializing string test_str = 'geeksforgeeks' # printing original string print("The original string is : " + str(test_str)) # computing half index hlf_idx = len(test_str) // 2 res = '' for idx in range(len(test_str)): # uppercasing later half if idx >= hlf_idx: res += test_str[idx].upper() else : res += test_str[idx] # printing result print("The resultant string : " + str(res)) |
The original string is : geeksforgeeks The resultant string : geeksfORGEEKS
Method #2 : Using list comprehension + join() + upper()
This is similar to above method, just the task is performed in shorthand manner using list comprehension.
Python3
# Python3 code to demonstrate working of # Uppercase Half String # Using list comprehension + join() + upper() # initializing string test_str = 'geeksforgeeks' # printing original string print("The original string is : " + str(test_str)) # computing half index hlf_idx = len(test_str) // 2 # join() used to create result string res = ''.join([test_str[idx].upper() if idx >= hlf_idx else test_str[idx] for idx in range(len(test_str)) ]) # printing result print("The resultant string : " + str(res)) |
The original string is : geeksforgeeks The resultant string : geeksfORGEEKS
