Input:
JavaScript
Output:
157

Sample Solution-1:

Python Code:

# License: https://bit.ly/3oLErEI

# Define a function named 'test' that takes a string 'strs' as input
def test(strs):
    # Use the 'filter' function to extract uppercase characters and 'map' to get their ASCII values
    # Finally, calculate the sum of ASCII values of uppercase characters
    return sum(map(ord, filter(str.isupper, strs)))

# Assign a specific string 'strs' to the variable
strs = "PytHon ExerciSEs"

# Print the original string 'strs'
print("Original strings:")
print(strs)

# Print a message indicating the operation to be performed
print("Sum of the ASCII values of the upper-case characters in the said string:")

# Print the result of the test function applied to the 'strs' string
print(test(strs))

# Assign a different string 'strs' to the variable
strs = "JavaScript"

# Print the original string 'strs'
print("\nOriginal strings:")
print(strs)

# Print a message indicating the operation to be performed
print("Sum of the ASCII values of the upper-case characters in the said string:")

# Print the result of the test function applied to the updated 'strs' string
print(test(strs))

Sample Output:

Original strings:
PytHon ExerciSEs
Sum of the ASCII values of the upper-case characters in the said string:
373

Original strings:
JavaScript
Sum of the ASCII values of the upper-case characters in the said string:
157

Sample Solution-2:

Python Code:

# License: https://bit.ly/3oLErEI

# Define a function named 'test' that takes a string 'strs' as input
def test(strs):
    # Initialize a variable 'tot' to store the total ASCII value of uppercase characters
    tot = 0
    
    # Iterate through each character 'c' in the string 'strs'
    for c in strs:
        # Check if the character is uppercase using 'isupper()' method
        if c.isupper():
            # If uppercase, add its ASCII value to 'tot'
            tot += ord(c)
    
    # Return the total ASCII value of uppercase characters
    return tot

# Assign a specific string 'strs' to the variable
strs = "PytHon ExerciSEs"

# Print the original string 'strs'
print("Original strings:")
print(strs)

# Print a message indicating the operation to be performed
print("Sum of the ASCII values of the upper-case characters in the said string:")

# Print the result of the test function applied to the 'strs' string
print(test(strs))

# Assign a different string 'strs' to the variable
strs = "JavaScript"

# Print the original string 'strs'
print("\nOriginal strings:")
print(strs)

# Print a message indicating the operation to be performed
print("Sum of the ASCII values of the upper-case characters in the said string:")

# Print the result of the test function applied to the updated 'strs' string
print(test(strs))

# Assign another string 'strs' to the variable
strs = "ARt"

# Print the original string 'strs'
print("\nOriginal strings:")
print(strs)

# Print a message indicating the operation to be performed
print("Sum of the ASCII values of the upper-case characters in the said string:")

# Print the result of the test function applied to the updated 'strs' string
print(test(strs))
