if循环，range生成数列，\n的用法

The “indentationerror: unindent does not match any outer indentation level” error is raised when you use both spaces and tabs to indent your code.

在if循环中报错：tab和space混用

numbers = list(range(1,10))

print(numbers)

for number in numbers:

    if number == 1:

        print("1st")

    elif number == 2:

        print("\n2nd")

    else:

        print("\n" + str(number) + "th")

range生成数列：numbers = list(range(1,10))，要加list（）

\n加引号

还有记得用str（）
