define function remove, given a string and a target character, return a string with all appearances of the target in the original string removed. The original string is not changed. Suppose the original string is "hello, hey" and the target character is 'h', then the returned string is "hello, ey". For the same original string, if the target is 'b', then the return is "hello, hey" (same as the original string). Your tasks: (a) Assume that necessary libraries are included. Define the above function. (b) In main function, write a statement to get the return of calling the above function with arguments "hello, hey: and 'I'. No need to write other parts of main function. (c) Write the expected return of Step (b)
Question
define function remove, given a string and a target character, return a string with all appearances of the target in the original string removed. The original string is not changed. Suppose the original string is "hello, hey" and the target character is 'h', then the returned string is "hello, ey". For the same original string, if the target is 'b', then the return is "hello, hey" (same as the original string). Your tasks: (a) Assume that necessary libraries are included. Define the above function. (b) In main function, write a statement to get the return of calling the above function with arguments "hello, hey: and 'I'. No need to write other parts of main function. (c) Write the expected return of Step (b)
Solution
(a) Here is the function definition in Python:
def remove(original_string, target_character):
return original_string.replace(target_character, '')
This function uses the replace method of the string class in Python. It replaces all occurrences of the target_character in the original_string with an empty string, effectively removing them.
(b) Here is the statement in the main function:
result = remove("hello, hey", 'l')
This statement calls the remove function with the arguments "hello, hey" and 'l'. The return value of the function call is assigned to the variable result.
(c) The expected return of Step (b) is "heo, hey". This is because all occurrences of the character 'l' are removed from the original string "hello, hey".
