Given a String extract indices of uppercase characters.
Input : test_str = ‘GeeKsFoRGeeks’
Output : [0, 3, 5, 7, 8]
Explanation : Returns indices of uppercase characters.Input : test_str = ‘GFG’
Output : [0, 1, 2]
Explanation : All are uppercase.
Method #1 : Using list comprehension + range() + isupper()
In this we iterate through the indices till string length, and check for uppercase character using isupper(), if found, index is recorded.
Python3
# Python3 code to demonstrate working of # Uppercase Indices# Using list comprehension + range() + isupper() # initializing stringtest_str = 'GeeKsFoRGEEks' # printing original stringprint("The original string is : " + str(test_str)) # Uppercase check using isupper()res = [idx for idx in range(len(test_str)) if test_str[idx].isupper()] # printing result print("Uppercase elements indices : " + str(res)) |
The original string is : GeeKsFoRGEEks Uppercase elements indices : [0, 3, 5, 7, 8, 9, 10]
Method #2 : Using enumerate() + isupper()
In this, the indices are captured using enumerate(), and isupper() does task of uppercase check as in above method.

The original string is : GeeKsFoRGEEks Uppercase elements indices : [0, 3, 5, 7, 8, 9, 10]
