Consider using join

Using str.join(sequence) is faster, uses less memory and increases readability compared to for-loop iteration.

Noncompliant Code:

Copy

def fruits_to_string(fruits):
    formatted_fruit = ""
    for fruit in fruits:
        formatted_fruit += fruit
    return formatted_fruit

print(fruits_to_string(["apple", "pear", "peach"]))

Compliant Code:

Copy

print("".join(["apple", "pear", "peach"]))
