Question

我正在运行：

def add (a, b):
    print "ADDING %d + %d" % (a, b)
    return a + b

def subtract (a, b):
   print "SUBSTRACTING %d - %d" %(a, b)
   return a -b

def multiply (a, b):
    print "MULTIPLYING %d * %d" % (a, b)
    return a * b

def devide (a, b):
    print "DEVIDING %d / %d" % (a, b)
    return a / b

print " lets do some math with just function!"


age = add(30, 5)
hight = subtract (78, 4)
weight = multiply (90, 2)
iq = divide = (100, 2)

print "Age: %d, Hight: %d, Weight: %d, IQ: %d" % (age, hight, weight, iq)

我得到了这个：

TypeError: %d format: a number is required, not tuple

但为什么？

Answer 1

您的代码中只有一些错字：

iq = divide = (100, 2)

def devide (a, b):

需要成为

iq = divide(100, 2)

def divide (a, b):

TypeError：％d format：需要一个数字，而不是元组
