在python中，如何从用户那里获取输入并在输入后跳转到不同的行？

Question

am new to python and was working on the following code (program to find average)

sum=0
for i in range(1,9999):
    n=int(input("Enter your number: "))
    i+=1
    sum=n+sum
    a=input("Do you want to add more (Y/N): ")
    if a=="Y" or a=="y":
        continue
    elif a=="N" or a=="n":
        break
    else:
        print("Error: Incorrect choice")
i-=1
avg=sum/i
print(avg)

All good, but if the user inputs "Incorrect choice" how can I make it jump to the "if statement" where it asks the user again whether he/she wants to add more number? In structured programming I think "goto" or "label" can be used, but python is object oriented, how can I make it work here. Please advice.

Answer 1

there are several way you can use "while"

while a not in ["Y","y","N","n"]:
    a=input("Do you want to add more (Y/N): ")
