What are local variables and global variables in Python?

Global Variables:

Variables declared outside a function or in a global space are called global variables. These variables can be accessed by any function in the program.

Local Variables:

Any variable declared inside a function is known as a local variable. This variable is present in the local space and not in the global space.

Example:

a=2

def add():

b=3

c=a+b

print(c)

add()

What is PYTHONPATH?

Ans: It is an environment variable that is used when a module is imported. Whenever a module is imported, PYTHONPATH is also looked up to check for the presence of the imported modules in various directories. The interpreter uses it to determine which module to load.

What is _init_?

Ans: _init_ is a method or constructor in Python. This method is automatically called to allocate memory when a new object/ instance of a class is created. All classes have the _init_ method.

What are the generators in python?

Ans: Functions that return an iterable set of items are called generators

Age and Gender Detection In Python - Creation Code

Gender Identity: Gender identity is the personal sense of one's own gender . Gender identity can correlate with a person's assigned sex or can differ from it. In most individuals, the various biological determinants of sex are congruent and consistent with the individual's gender identity. Gender expression typically reflects a person's gender identity, but this is not always the case. While a person may express behaviors, attitudes, and appearances consistent with a particular gender role , such expression may not necessarily reflect their gender identity. The term gender identity was coined by Robert J Stoller in 1964. Modules and assets: In this project, we will use the assetsOpenCV library which will help us to play with the camera We also use some datasets to identify the faces and ages you can find those datasets here Explanation: We will first train our models test.py import cv2 def faceBox ( net , frame , conf_thresho...

Create Ping Pong Game in Python

Ping Pong Game: Table tennis , also known as ping-pong and whiff-whaff , is a sport in which two or four players hit a lightweight ball, also known as the ping-pong ball, back and forth across a table using small rackets. The game takes place on a hard table divided by a net. Except for the initial serve, the rules are generally as follows: players must allow a ball played toward them to bounce once on their side of the table and must return it so that it bounces on the opposite side at least once. A point is scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. Spinning the ball alters its trajectory and limits an opponent's options, giving the hitter a great advantage. We can make it using pygame but I keep it more simple we will create this game using only the turtle module so let's drive into the code without wasting any time Code: # Import required library import turtle # Create screen sc = turtle . Scre...

How To Draw BMW Logo - In Python

I know I don't need to introduce BMW as it is a very popular luxury car. Today we gonna draw the BMW logo in python. I know that you can draw it using a pencil and other tools like AutoCAD etc. But we are programmers we talk with computers so let's tell our computer to draw this logo for use with the help of python. Module The only module we will use is that turtle Code: import turtle as t t.begin_fill() t.fillcolor( '#008ac9' ) for i in range ( 50 ): t.forward( 4 ) t.left( 2 ) t.right(- 80 ) t.forward( 116 ) t.right(- 90 ) t.forward( 132 ) t.end_fill() t.penup() t.pendown() t.right( 90 ) for i in range ( 50 ): t.forward( 4 ) t.left(- 2 ) t.right( 80 ) t.forward( 116 ) t.forward(- 116 ) t.right( 90 ) t.begin_fill() t.fillcolor( '#008ac9' ) for j in range ( 45 ): t.forward(- 4 ) t.left(- 2 ) t.right(- 90 ) t.forward( 116 ) t.end_fill() t.right( 180 ) t.forward( 116 ) t.right( 90 ) for i in ...
