Python: Alternate the case of each letter in a given string and the first letter must be uppercase

Python Basic - 1: Exercise-134 with Solution

Write a Python program that alternates the case of each letter in a given string, with the first letter in the string being uppercase.

Sample Solution

Python Code:

def test(txt):
    result_str = ""
    s = True
    for i in txt:
        result_str += i.upper() if s else i.lower()
        if i.isalpha():
            s = not s
    return result_str
str1 = "Python Exercises";
print("Original string: ", str1);
print("After alternating the case of each letter of the said string:")
print(test(str1))
str1 = "C# is used to develop web apps, desktop apps, mobile apps, games and much more.";
print("\nOriginal string: ", str1);
print("After alternating the case of each letter of the said string:")
print(test(str1))  

Sample Output:

Original string:  Python Exercises
After alternating the case of each letter of the said string:
PyThOn ExErCiSeS

Original string:  C# is used to develop web apps, desktop apps, mobile apps, games and much more.
After alternating the case of each letter of the said string:
