python 基础 3 if语句

sex = input("please input your gender:")
if sex == "man":
    print("I would like to makefriend with you")
elif sex == "girl":
    print("I would like have a little monkey with you")
else:
    print("are you kidding me?")

python里面采用强制缩进，来指定作用域。类似于java里面的{}括起来的部分。如果没有缩进的话，python就会语法错误。
python只会认为要执行if下有缩进的那些语句。
