Question

嘿伙计我正在使用Python进行编程，并且我在main函数中不断出现语法错误。在if语句之后， “if points＆gt; = 9＆lt; = 51：”Python告诉我冒号是语法错误。我写了类似于这个任务的python代码，我似乎无法找到问题。任何人都可以帮助我吗？

非常感谢。

def variable(points):
if points >= 9 <= 51:
    print('Valid Points')
else:
    print('Invalid Points')

return points

def main():
points = int(input('Enter how many points you scored: ')
if points >= 9 <= 51:
    points = variable(points)
else:
    points = variable(points)

main()

Answer 1

你的语法和缩进有点偏。尝试

>>> def variable(points):
...     if 9<= points<= 51:
...          print('Valid Points')
...     else:
...         print('Invalid Points')
...
...
>>> variable(34)
Valid Points

同样适用于你的def main():，并且

中也缺少一个副词

points = int(input('Enter how many points you scored: ')

Answer 2

除了不平等问题，您忘记了尾随)：

points = int(input('Enter how many points you scored: ')

Answer 3

缩进是错误的，并且缺少括号。

def variable(points):
    if points >= 9 <= 51:
        print('Valid Points')
    else:
        print('Invalid Points')

    return points

def main():
    points = int(input('Enter how many points you scored: '))
    if points >= 9 <= 51:
        points = variable(points)
    else:
        points = variable(points)

main()

Answer 4

你忘了关闭一个人。

points = int(input('Enter how many points you scored: '))

if语句中的Python语法错误
