Python first step starting from basics (i)

1. First Python program

Print " hello,world! "# After seeing it I couldn't help but put parentheses and semicolons. 

2. Variables

Name = "Wenjinli" age = #这么不正经的写法, even without distinguishing between variable types

3.for Cycle

Age = 56for I in range (3):   #想当年在OC里面是这样写的 for (nsstring*str in array) uh ....    _age = Int (input (' gessage: '))    if age = = _age:        print (' congratulation! ')        Break    Elif Age > _age:        print (' Think bigger ')    else:        print (' Think smaller! ') else:    print (' You have tried too Manylallala times ') #刷新三观的认知, actually add else after for loop

For I in range (9):
    For j in Range (9):
        result = (i+1) * (j+1)
        Print ("{0}*{1}={2}". Format (i+1,j+1,result)) #99乘法表

4.while Cycle

Count =0 whileCount < 3: _age= Int (Input ('Gessage:'))    ifAge = =_age:Print('congratulation!')         Break    elifAge >_age:Print('think bigger')    Else:        Print('Think smaller!') Count+ = 1Else:    Print('You have tried too many times') #while竟然也可以加else
