Escape Sequence

 An escape sequence refers to a combination of characters beginning with a back slash (\) followed by letters or digits. Escape sequences represent non-printable and special characters in character and literal strings. As such, they allow users to communicate with a display device or printer by sending non-graphical control characters to specify actions like question marks and carriage returns.

Dictionary and Sets in Python

 Dictionary d={     "key1":"value1"     "key2":"value2" } d[key1] # output = value1  # will show error if key is incorrect Keys need to be of immutable data types eg, string,tuple or int  every key is unique,d is unordered [so no indexing]**,mutable Dictionary methods: d.keys()==print value of all keys as list (class=dict_keys) (list) output as dict_keys([list of keys]) d.values()==print all the values(list) output as dict_values([list of values]) d.items()== create a list of multiple tuples each having 2 elements :1 key and 1 value. output as dict_items([list of tuples]) d.update(d2)==add new item(s) of d2 in original dictionary at the end. or d[new_key]=new_value d.update("old_key","new_value")==replaces old value with new value d.get("key",error_message/value)== shows the related value or none # no error[default error message=None] print(d.get(...)) d.pop("key") d.clear() d.fromkeys(<a list of keys...

Grid Printing Code for Python

 Github link : Click here Note: The code is open-source  but it highly advised to acknowledge this Web page or the github link whenever using this code in your project . The main aim of this is to allow for easy access to a 2d grid with x,y coordinates. It can be used to create a chess board, Maze or just anything you could think of with a grid.  The basic output look as follows: The variables defined are: The function in it are:  For customization : Change the variable x,y to alter the board size  Insert values in the _coords lists to get a particular pattern in a certain cell If you want to change the default cell filling then simply go to the end of print_board() function and under the heading default change the empty_cell function to any desired functions. I hope this code will help you sometime in future or it gave you an idea to make a better version of it (then don't forgot to share it to me via commenting it down).  Github link of the whole code:...
