Answer on Question #62199, Programming & Computer Science / Python

You need to design an iterative and a recursive function called replicate_iter and replicate_recur respectively which will receive two arguments: times which is the number of times to repeat and data which is the number or string to be repeated.

Solution:

Iterative function using while loop:

def replicate_iter(n, dat):
    answer = ""
    k = 0
    while k < n:
        answer = answer + str(dat)
        k += 1
    return answer

Examples:

print(replicate_iter(5, 6))
print(replicate_iter(2, "123abcd"))
66666
123abcd 123abcd

Recursive function (calls itself):

def replicate_recur(n, dat):
    if n <= 0:
        return ""
    else:
        return replicate_recur(n - 1, dat) + str(dat)

Examples:

print(replicate_recur(5, 6))
print(replicate_recur(2, "abcd123"))
66666
abcd123 abcd123

Screenshot of both functions:

1 def replicate_iter(n, dat):
2     answer = ""
3     k = 0
4     while k < n:
5         answer = answer + str(dat)
6         k += 1
7     return answer

10     if n <= 0:
11         return ""
12     else:
13         return replicate_recur(n - 1, dat) + str(dat)
