python while it if elif

1.raw_input関数

name=raw_input("what is your name?")
age=raw_input("how old are you?")
print name +"is" +age

2.if文

hasBiscuits=raw_input("do you have a biscuits???")
if hasBiscuits=="yes":
    print "it seems very delicious!"#        ，    tab
else:
    print"you have trick me！！！"

ネストif文:

hasBiscuits=raw_input("do you have a biscuits???")
if hasBiscuits=="yes":
    print "it seems very delicious!"
    canHave=raw_input("can you give some for me ?")
    if canHave=="yes" :
        print "thank your!!"#        ！
    else :
        print "I am angry!"
else:
    print"you have trick me！！！"

elif:elifはelse ifの略で、if文と並ぶ文です.

hasBiscuits=raw_input("do you have a biscuits???")
if hasBiscuits=="yes":
    print "it seems very delicious!"
    canHave=raw_input("can you give some for me ?")
    if canHave=="yes" :
        print "thank your!!"
    else :
        print "I am angry!"
elif hasBiscuits== "no":
    print"you have trick me！！！"
elif hasBiscuits=="donnot know":
    print "are you foolish?"
else:
    print "hehe......"

3.whileループ文

username=raw_input("what is your name?")
message=raw_input("please input your message!")
while message!="exit":
    print username + ":" +message
    message=raw_input("please input your message!")

注意:判断文では、=を使用し、=を使用しない!=を使用します.while文もif文も括弧を使わず、直接while a=b:....
無限ループのwhile:

while True :
    print "you are great!!!"

4.if,elif,while総合実験

again="yes"
while again == "yes":
    praiseType=raw_input("select a type you like

 b:appearence 
 c:intellengence 
")
    if praiseType == "a":
        print "you are human!"

    again = raw_input ("do you want go on? input yes or no!")
