Assign Value Printing

name = "Hello, world"
msg = "I ' m Alex Li"

Print (name)
Print (msg)

#单行注释

"""
Multi-line comments
"""

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

Three modes of output:
One:
Splicing method, not recommended, each time to open up new memory

Two:

Info2 = "'
----info of {_name}----
Name:{_name}
Age:{_age}
Job:{_job}
Salary:{_salary}
". Format (_name = name,
           _age = age,
           _job = Job,
           _salary = salary)
Print (Info2)

Three:

Info3 = "'
----info of {0}----
NAME:{0}
Age:{1}
JOB:{2}
SALARY:{3}
". Format (name, age, job, salary)
Print (INFO3)

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

Condition Judgment:

Import Getpass

#密文导入框架 (terminal display)

#存密码
_username = ' Zhou '
_password = ' abc123 '
Username = input ("Username:")
#password = Getpass.getpass ("Password:")
Password = input ("Password:")


#if Else logic
#else强制缩进
If _username = = Username and _password = = password:
    #if的子代码
    Print ("Welcome to user {name} python". Format (Name=username))
Else
    #else的子代码
    Print ("Invalid username or password!")

Print ("My Tina")

---------------------------------------------------------------------
While loop:

Count = 0
While True:
    Print ("Count:", count)
    Count = count + 1   #count + = 1

    if Count = = 10:
        Break

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

Three input exercises:

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")
    Elif guess_age > Age_of_oldboy:
        Print ("Think smaller ...")
    Else
        Print ("Think bigger ...")
    Count + = 1
    Print ("Count:", count)

Else
    Print ("Sorry, you have used up the number of times")

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

For loop Printing:

#循环10次  range equals the set of variables, a set of data 0-9

#打印0, 2,4,6,8    0,10,2
#打印1, 3,5,7,9    1,10,2

For I in range (0, 10, 3):
    Print ("Loop", i)

For I in range (10):
    Print ("Loop", i)

Nesting of For loops:

For I in range (4):
    Print ("-------", i)
    For j in Range (4):
        Print (j)
        If J > 1:
            Break
