python 语言问题

我最近在学python语言，最近老师给发了两个个改错题，我看了几次没看出来，求大神帮忙看看指点指点
1.

while True:
print("Enter a number operation (+, -, /, *, **, %):")
o = input()

print("Input your first number")
f = input()

print("Input your second number:")
s = input()

if o == '%':
print(f % s)
if o == '**':
print(f ** s)
if o == '*':
print(f * s)
if o == '/':
print(f / s)
if o == '-':
print(f - s)
if o == '+':
print(f + s)

print("Are you done? (no or yes)")
answer = input()

if answer == "no":
break

2.

choice = 1
while choice == 1:
print("Choose an operation:")
print("1. +")
print("2. -")
print("3. *")
print("4. /")
print("5. %")
print("6. **")

op = -1
while op < 1 or op > 6:
op = int(input())

x = input("Enter first number:")
y = input("Enter second number:")

if op == 1:
print(x+y)
elif op == 2:
print(x-y)
elif op == 3:
print(x*y)
elif op == 4:
print(x/y)
elif op == 5:
print(x%y)
elif op == 6:
print(x**y)

choice = int(input("Enter 1 if you want to continue:"))

Answer 1

2个题目都是一样的错误,input() 返回档手字符串,无论你是输入字母还是数字都当雹伍作字符串处理,如源蠢或果要做数学运算,要先用int()函数转换成数字

追问

麻烦能帮忙指出哪里出现错误了吗，你是指在input前加int？
