bis python basis: placeholder, formatted output, while else, logic operations

1, output formatting and placeholders

Sample Code

1  # formatted output 
2  # % SD 
. 3  # name = INPUT ( 'Enter your name') 
. 4  # Age = INPUT ( 'Enter Age') 
. 5  # height = INPUT ( 'Enter height') 
. 6  # MSG = " my name is% s, year% s height% s "% (name, Age, height) 
7  # Print (msg) 
8  " "" 
9  name = the iNPUT ( 'Please enter your name:')
 10  Age = the iNPUT ( 'Please enter Age: ')
 11  the job the iNPUT = (' Please enter the work: ')
 12  Hobbie = the iNPUT (' your hobby: ')
 13  
14  msg =' '' ------------ info of% ----------- S
 15  the Name:
%s
16 Age   : %d
17 Job:% S
 18 is  Hobbie:% S
 . 19  ------------- End ----------------- '' '% (name, name, int (Age), Job, Hobbie)
 20 is  Print (MSG)
 21 is  "" " 
22 is name = iNPUT ( ' enter your name ' )
 23 is Age = iNPUT ( ' enter Age ' )
 24 height = iNPUT ( ' enter height ' )
 25 msg = " my name is% s,% s this height is% s learning progress %% S 3 " % (name, Age, height)
 26  Print (msg)

 2, while else statements

. 1 COUNT = 0
 2  the while COUNT <=. 5 :
 . 3      COUNT + =. 1
 . 4      IF COUNT ==. 3: BREAK 
. 5      Print ( " Loop " , COUNT)
 . 6  
. 7  the else :
 . 8      Print ( " loop done for normal execution " )
 . 9  Print ( " ----- ------ OUT of the while Loop " )

3, the logic

 1 #and or not
 2 #优先级，（）> not > and > or
 3 # print(2 > 1 and 1 < 4)
 4 # print(2 > 1 and 1 < 4 or 2 < 3 and 9 > 6 or 2 < 4 and 3 < 2)
 5 # T or T or F
 6 #T or F
 7 # print(3>4 or 4<3 and 1==1)  # F
 8 # print(1 < 2 and 3 < 4 or 1>2)  # T
 9 # print(2 > 1 and 3 < 4 or 4 > 5 and 2 < 1)  # T
10 # print(1 > 2 and 3 < 4 or 4 > 5 and 2 > 1 or 9 < 8)  # F
11 # print(1 > 1 and 3 < 4 or 4 > 5 and 2 > 1 and 9 > 8 or 7 < 6)  # F
12 # Print (Not 2>. 3. 1 and <. 4. 4 or>. 5 and 2>. 9. 1 and> or. 8. 7 <. 6) F. # 
13 is  
14  # PS int ----> BOOL converted to the nonzero converted bool True 0 bool is False 
15  # Print (bool (2)) 
16  # Print (bool (-2)) 
. 17  # Print (bool (0)) 
18 is  # #bool ---> int 
. 19  # Print (int (True)) # . 1 
20 is  # Print (int (False)) # 0 
21 is  
22 is  
23 is  '' ' X or YX True, it returns X ' '' 
24  # Print (. 1 or 2) #. 1 
25  # Print (. 3 or 2) #. 3 
26 is  # Print (or 0 2) # 2
27 # print(0 or 100)  # 100
28 
29 
30 # print(2 or 100 or 3 or 4)  # 2
31 
32 # print(0 or 4 and 3 or 2)
33 '''x and y x True，则返回y'''
34 # print(1 and 2)
35 # print(0 and 2)
36 print(2 or 1 < 3)
37 print(3 > 1 or 2 and 2)
