Question

Write a function named concat_keys whose parameter is an object/dictionary. The parameter will have strings as keys and integers as values. The function should return a string whose value is the concatenation of the parameter's keys with a space added after each key.(in python)

Answer 1

The concat_keys function in Python concatenates the keys of a given dictionary, adding a space after each key and returns the resulting string without a trailing space.

Step-by-step explanation:

The function concat_keys will take a dictionary as an input and return a string that is a concatenation of the keys of the dictionary. Each key will be followed by a space. The function iterates over the keys of the dictionary using a for loop and appends each key along with a space to a string result. The strip method is used at the end to remove the trailing space.

Here is an example of the Python function:

def concat_keys(my_dict):
result = ''
for key in my_dict.keys():
result += key + ' '
return result.strip()

When you call this function with a dictionary, it will return a string of the keys separated by spaces.
