Created: List = [5,7,9]
Value and change: list[1] = list[1] * 5
End of List insert: List.append (4)
Subtract the No. 0 value and return the value of the No. 0 value: List.pop (0)
Remove the No. 0 value without returning a value: Del (list[0])
Remove a specific value: List.remove (35)
function functions:
No parameters: Def function ():
One parameter: def function (x):
2 Parameters: def function (y):
Any of the parameters: Def add_function (*args):
function Range:
One parameter: Range (n) starts from No. 0 digit n digit
Two parameters: Range (m,n) starts from the first m bit to the n-1 bit, with an increment interval of 1
Three parameters: Range (m,n,i) starts from the first m bit to the n-1 bit, with an increment interval of I
For item in list: And for I in range (len (list)): equivalent
Use separator as the interval output for elements in list: print Separator.join (list)
For example: List = [' A ', ' B ', ' C ', ' d '] The general print List will output: [' A ', ' B ', ' C ', ' d '].
and print "". Join (list) outputs: a B c D (must be double quotes, single double quotes do not work)
Accept Keyboard Input:
guess_row = Int (raw_input ("Guess row:"))
Here is a small program that you write yourself: Generate a square and a random position, and ask the player to guess where the generated position is
Copy CodeThe code is as follows:
From random import Randint
def creat_board (length):
board = []
For I in range (length):
Board.append ([' O '] * length)
Return board
def print_board (x):
For row in x:
Print "". Join (Row)
def random_row (board):
Return Randint (0, Len (board)-1)
def random_col (board):
Return Randint (0,len (board[0])-1)
length = Int (raw_input ("Enter board ' s length you:"))
board = creat_board (length)
Print_board (board)
turns = Int (raw_input ("Enter turns want to play:"))
For turn in range (turns):
Ship_row = Random_row (board)
Ship_col = Random_col (board)
Print "This was" + STR (turn + 1) + "th time to guess:"
guess_row = Int (raw_input ("Enter The row You guess:"))
guess_col = Int (raw_input ("Enter the col You guess:"))
if Guess_row = = Ship_row and Guess_col = = Ship_col:
Print "You win!"
Break
Else
if (Guess_row < 0 or Guess_row > len (Board)-1) or (Guess_col < 0 or Guess_col > len (Board)-1):
print "Incorrect input!"
if turn = = turns-1:
Print "Turns out!"
Elif Board[guess_row][guess_col] = = ' X ':
Print "You have guessed it already!"
if turn = = turns-1:
Print "Turns out!"
Else
Print "You guess wrong!"
Board[guess_row][guess_col] = ' X '
Print_board (board)
if turn = = turns-1:
Print "Turns out!"
Mistakes that have been made:
1. Create board function forget to return a board, so it has been empty, resulting in the subsequent operations are out of bounds;
2. When generating random positions, the naming of the row and Col is always the same as the generated function name (Random_row=random_row (board)), resulting in typeerror: ' int ' object is not callable error.
