1.python格式化输出

 name = input ("name:")

 age = int(input("age:"))

 info = '''

---------- info of %s ----------

Name:%s

Age:%s

'''%(name, age)

2.if else语句

age=36

if age == int(intput("age:")):

  print("yes,you got it")

else:

  print("you are wrong")

---------------------------------------

------------if elif else---------------

age=36

if age == int(input("age:")):

  print("yes,you got it")

elif age > int(input("age:")):

  print("is smaller")

else:

  print("is bigger")

--------------------------------------

--------while----------

i=1

while i < 3:

   print("i:"i)

   i +=i

--------------------------------------

----------------for------------------

for i in range(10):

  print("i:"i)

上式等价于

for i in range(0,10,1):

   print("i:")

(0,10,1)中，1的意思是步长，(0,10,2)这样会隔一个数输出，0，2，4，6，8
