類型錯誤：％d格式：需要數量，而不是元組

Question

我運行此：

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) 

我得到這個：

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

但爲什麼呢？

Answer 1

只是一些錯字在你的代碼：

iq = divide = (100, 2) 

def devide (a, b): 

需要成爲

iq = divide(100, 2) 

def divide (a, b):
