Python BASICS (1): python Basics

1. Dynamic Assignment Method

Name = input ("name :")
Age = int (input ("age :"))
Print (type (age ))
Job = input ("job :")

Info = '''
------ Info of % s ------
Name: % s
Age: % s
Job: % s
''' % (Name, name, age, job)


Info1 = '''
------ Info of {0 }------
Name: {0}
Age: {1}
Job: {2}
'''. Format (name, age, job)


Info2 = '''
------ Info of {_ name }------
Name: {_ name}
Age: {_ age}
Job: {_ job}
'''. Format (_ name = name, _ age = age, _ job = job)
Print (info)
Print (info1)
Print (info2)

2. Enter the verification age

Age_of_oldboy = 56
Count = 0
While count <3:
Guess_age = int (input ("guess age :"))
If guess_age = age_of_oldboy:
Print ("yes, you got it .")
Break
Elif guess_age> age_of_oldboy:
Print ("think smaller ...")
Else:
Print ("think bigger! ")
Count + = 1;
Else:
Print ("you have tried too times... fuck off ")

3. user name and password verification

Import getpass

_ Username = 'iefei'
_ Password = 'xf123'

Username = input ("username :")
Password = input ("password :")

If _ username = username and _ password = password:
Print ("Welcome user {name} login...". format (name = username ))
Else:
Print ("Invalid username or password! ")

Print ("end ")

Print (username, password)

4. for Loop

For I in range (0, 10 ):
If I <5:
Print ("loop", I)
Else:
Continue
Print ("hehe ...")
