Python: Sum the length of the names of a given list of names after removing the names that starts with a lowercase letter

Python Lambda: Exercise-22 with Solution

Write a Python program that sums the length of a list of names after removing those that start with lowercase letters. Use the lambda function.

Sample Solution:

Python Code :

# Create a list of strings named 'sample_names' containing various names
sample_names = ['sally', 'Dylan', 'rebecca', 'Diana', 'Joanne', 'keith']

# Filter the 'sample_names' list using a lambda function to include only names that start with an uppercase letter
# followed by lowercase letters for the rest of the name
sample_names = list(filter(lambda el: el[0].isupper() and el[1:].islower(), sample_names))

# Print a label for the upcoming result
print("Result:")

# Calculate the total length of the concatenated string formed by joining all the filtered names together
print(len(''.join(sample_names))) 

Sample Output:

Result:
16
