2. Basic syntax for Python language

(1) Defining variables

1 a =2 b = 23 c = a + b

(2) Judgment statement

1Score = 902 3 ifScore >= 80 :4    Print("Excellent")5 elifScore >= 70 :6    Print("Medium")7 elifScore >= 60 :8   Print("Pass")9 Else:Ten    Print("inferior lattice")

(3) Cycle

1  forIinchRange (0,5,2):2    Print(i)3 Print("================")4  forIinchRange (0,5):5    Print(i)6 Print("================")

Print ("Item {0} {1}". Format ("eee"))

For I in Range (0,5):
   Print (i)
Else
   Print ("Loop End")

(4) function

1 defSayHello ():2    Print("Hello World")3 4 SayHello ()5 6 defMymax (x, y):7    ifX >y:8       PrintX"is Max"9    Else:Ten       PrintY"is Max" OneMymax (10,9) A  - defmymaxval (x, y): -    ifX >y: the       returnx -    returny -  - Print(Mymaxval (10,8))

(5) Object

1 classHello:2    def __init__(self, name):3Self.name =name4       Print("Hello Constructor")5    def __del__(self):6       Print("Hello destructor")7 8    defSayHello (self):9       Print("Hello {0}". Format (self.name))Ten  One classHi (Hello): A    def __int__(self,name): -Hello.__init__(Self,name) -Self.name =name the       Print("Hi constructor Function") -  -    defSayhi (self): -       Print("Hi {0}". Format (self.name)) +  - #Hello Object +H = Hello ("Zhangsan") A H.sayhello () at  - #Hi Object -hi = Hi ("Lisi") - Hi.sayhi () -Hi.sayhello ()
