Question

def new_string(str):
if len(str) >= 2 and str[:2] == "Is":
return str
return "Is" + str

print(new_string("Array"))
print(new_string("IsEmpty"))

Answer 1

The if statement checks if the given value is 2 or more and if the first letter is I and the second letter’s s. If so the function will return the given value (function always stops after it returns). If the statement is false it will return Is + the given value.
