这段代码有错误吗？如果是让我知道？

Question

a = int(input("Enter Your First Number="))
b = int(input("\nEnter Your Second Number="))

def cal():
    sum = a + b
    sub = a - b
    mul = a * b
    div = a % b

cal()    
print("\nAddtion of Two Number is =" , sum)
print("\nSubtraction of Two Number is =" , sub )
print("\nMultiplication of Two Number is =" , mul  )
print("\nDivision of Two Number is =" , div  )

I can't find the exact output I'm a beginner So guide me please,

Answer 1

您需要使函数 return 的值：

a = int(input("Enter Your First Number="))
b = int(input("\nEnter Your Second Number="))

def cal():
    sum = a + b
    sub = a - b
    mul = a * b
    div = a % b
    return sum, sub, mul, div

sum, sub, mul, div = cal()    
print("\nAddtion of Two Number is =" , sum)
print("\nSubtraction of Two Number is =" , sub )
print("\nMultiplication of Two Number is =" , mul  )
print("\nDivision of Two Number is =" , div  )

Answer 2

您必须return这些值才能在函数外使用它们

a = int(input("Enter Your First Number="))
b = int(input("\nEnter Your Second Number="))

def cal():
    return a + b, a - b, a * b, a % b

add,sub,mul,div = cal()    
print("\nAddtion of Two Number is =" , add)
print("\nSubtraction of Two Number is =" , sub )
print("\nMultiplication of Two Number is =" , mul  )
print("\nDivision of Two Number is =" , div  )

Answer 3

您不能在函数外访问函数变量。 PLace 函数内的打印语句或函数中的 return 值，如下所述。
