学习python第一天的收获

第一，Hello World！

print("hello world!")

name ="robin liu"

name2 = name

print("My name is",name)

name = "paoche ge"

第二：学习注释

msg ='''
注释的问题
'''
print(msg)

第三流程判断

_name ='liu'
_pswd='123'
name = input("name")
pswd = input("pswd")

if _name == name and _pswd == pswd:
print("welcom user {name} login..".format(name=name))
else:
print("Invalid username or pswd!")

第四输入

name=input("name:")
age=int(input("age:"))
print(type(age))
job=input("job:")
salary=input("salary:")

"""
info = '''
----------info of '''+ name + '''-----
name:'''+ name + '''
age:'''+ age + '''
job:'''+ job +'''
salary:'''+salary+'''
'''

info = '''
----------info of %s-----
name:%s
age:%s
job:%s
salary:%s
'''%(name,name,age,job,salary)

info = '''
----------info of %s-----
name:%s
age:%s
job:%s
salary:%s
'''%(name,name,age,job,salary)

info = '''
----------info of {_name}-----
name:{_name}
age:{_age}
job:{_job}
salary:{_salary}
'''.format(_name=name,
_age=age,
_job=job,
_salary=salary)
"""
info = '''
----------info of {0}-----
name:{0}
age:{1}
job:{2}
salary:{3}
'''.format(name,age,job,salary)
print(info)
