Isolated Last Character Check

Write a Python program to check, for each string in a given list, whether the last character is an isolated letter or not. Return True otherwise False.

Input:
['cat', 'car', 'fear', 'center']
Output:
[False, False, False, False]

Input:
['ca t', 'car', 'fea r', 'cente r']
Output:
[True, False, True, True]

Sample Solution:

Python Code:

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

# Define a function named 'test' that takes a list of strings 'strs' as input
def test(strs):
    # List comprehension to check whether the last character of each string is an isolated letter
    return [len(s.split(" ")[-1]) == 1 for s in strs]

# Assign a specific list of strings 'strs' to the variable
strs = ['cat', 'car', 'fear', 'center']

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

# Print a message indicating the operation to be performed
print("Check, for each string in the said list, whether the last character is an isolated letter:")

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

# Assign a different list of strings 'strs' to the variable
strs = ['ca t', 'car', 'fea r', 'cente r']

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

# Print a message indicating the operation to be performed
print("Check, for each string in the said list, whether the last character is an isolated letter:")

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

Sample Output:

Original strings:
['cat', 'car', 'fear', 'center']
Check, for each string in the said list, whether the last character is an isolated letter:
[False, False, False, False]

Original strings:
['ca t', 'car', 'fea r', 'cente r']
Check, for each string in the said list, whether the last character is an isolated letter:
[True, False, True, True]

For more Practice: Solve these Related Problems:

• Write a Python program to check for each string in a list whether its last character is separated by a space from the preceding part.
• Write a Python program to determine if the last character of each string is isolated, meaning it is preceded by whitespace.
• Write a Python program to iterate over a list of strings and return True for those whose last character is not connected to the rest of the word.
• Write a Python program to split each string and verify if the final element is a standalone character.
