Python 根据数字打印星期几

Question

我正在创建一个程序，我必须输入一个数字，当我运行该程序时，解决方案应该是该数字的日期。但我不知道该怎么做。我做的程序是这样的：

num = 4
if(num = 1)
    print('Monday')
elif(num = 2)
    print('Tuesday')
elif(num = 3)
    print('Wednesday')
elif(num = 4)
    print('Thursday')
elif(num = 5)
    print('Friday')
elif(num = 6)
    print('Sunday')
elif(num = 7)
    print('Saturday')
elif(num < 1)
    print('Put a number between 1 and 7')
else(num > 7)
    print('Put a number between 1 and 7')

Answer 1

num = 0
while num <= 7:
    num += 1
    if num == 1:
        print('Monday')
    elif num == 2:
        print('Tuesday')
    elif num == 3:
        print('Wednesday')
    elif num == 4:
        print('Thursday')
    elif num == 5:
        print('Friday')
    elif num == 6:
        print('Saturday')
    elif num == 7:
        print('Sunday')

Answer 2

在python中，for语句如if、for等。你必须在它的末尾添加:。为了比较（相等），您必须使用 == 而不是 =

num = 4
if(num == 1):
    print('Monday')
elif num == 2:
    print('Tuesday')

.....

您可以不带括号进行比较，它也可以。
