Python输入与循环

python

while循环

while 语句:

  执行语句

  结束条件

#应用while输出1到11
counts = 1
while True:
    print("counts:", counts)
    counts = counts +1 #counts +=1
    if counts == 11:
        break

 for 循环

for 变量 in range(起始值,终止值,步长):

  循环语句

#从零开始以3为步长不超过10
for i in range(0,10,3)
    print(i)

python注释中获得输入信息的几种方式

方法1:

变量1 = input(“A”)

变量2 = input(“B”)

info = '''

C:%s

D:%s

'''%(变量1,变量2)

#输入姓名、年龄,输出姓名、年龄
name = input("name")
age = int(input("age"))
info = '''
-------------info of %s---------
name:%s
age:%d

'''%(name,name,age)
print(info)

方法2:

变量1 = input(“A”)

变量2 = input(“B”)

info = '''

C:{E}

D:{F}

'''.format(E=变量1,F=变量2)

 
info2 = '''
-------------info of {_name}---------
name:{_name}
age:{_age}

'''.format(_name=name,
           _age=age)
print(info2)

方法3:

变量1 = input(“A”)

变量2 = input(“B”)

info = '''

C:{0}

D:{1}

'''.format(变量1,变量2)

info3 = '''
-------------info of {0}---------
name:{0}
age:{1}

'''.format(name, age)

print(info3)

 简单登陆

#引入一个getpass
import getpass
#定义一个用户名和密码
_name = '123'
_password = '456'
#获得键盘输入值
name = input("name")
# password = getpass.getpass("password")
# 密码密文,pycharm不好使


password = input("password")
#判断用户名和密码是否一致
if _name == name and _password == password:
#将用户名传给输出语句中
    print("welcome user{name} login...".format(name = name))
    print("----------------")
else:
    print("Invalid password")

 猜大小小程序

number = 20
#for 循环  range(开始,结束,步长)
for i in range(1,10,2):
    #获得输入值
    guess_number = int(input("guess number:"))
    #进行比较
    if guess_number == number:
        print("yes, you got it.")
    elif guess_number > number:
        print("think smaller ...")
    else:
        print("think bigger!")
    print("loop",i)
