Python Operators Demystified

#python #operators #webdev #react

Python operators are symbols that perform operations on variables and values. They are used in various programming tasks, including arithmetic calculations, comparisons, logical operations, and more. Here's a detailed look at the different types of Python operators:

  1. Arithmetic Operators Arithmetic operators are used to perform mathematical operations.
  • + (Addition): Adds two operands. 
  x = 5 + 3   x will be 8
Enter fullscreen mode Exit fullscreen mode
  • - (Subtraction): Subtracts the second operand from the first. 
  x = 5 - 3   x will be 2
Enter fullscreen mode Exit fullscreen mode
  • (Multiplication): Multiplies two operands. python x = 5 3 x will be 15 ``
  • / (Division): Divides the first operand by the second. `python x = 5 / 2 x will be 2.5 `
  • % (Modulus): Returns the remainder of the division. `python x = 5 % 2 x will be 1 `
  • `` (Exponentiation): Raises the first operand to the power of the second. 
  x = 2  3   x will be 8

  • // (Floor Division): Divides the first operand by the second and returns the largest integer less than or equal to the result. 
  x = 5 // 2   x will be 2
Enter fullscreen mode Exit fullscreen mode
  1. Comparison Operators Comparison operators compare two values and return a boolean value (True or False).
  • == (Equal): Returns True if both operands are equal. 
  x = (5 == 3)   x will be False
Enter fullscreen mode Exit fullscreen mode
  • != (Not Equal): Returns True if operands are not equal. 
  x = (5 != 3)   x will be True
Enter fullscreen mode Exit fullscreen mode
  • > (Greater Than): Returns True if the left operand is greater than the right. 
  x = (5 > 3)   x will be True
Enter fullscreen mode Exit fullscreen mode
  • < (Less Than): Returns True if the left operand is less than the right. 
  x = (5 < 3)   x will be False
Enter fullscreen mode Exit fullscreen mode
  • >= (Greater Than or Equal To): Returns True if the left operand is greater than or equal to the right. 
  x = (5 >= 3)   x will be True
Enter fullscreen mode Exit fullscreen mode
  • <= (Less Than or Equal To): Returns True if the left operand is less than or equal to the right. 
  x = (5 <= 3)   x will be False
Enter fullscreen mode Exit fullscreen mode
  1. Logical Operators Logical operators are used to combine conditional statements.
  • and: Returns True if both statements are true. 
  x = (5 > 3 and 5 < 10)   x will be True
Enter fullscreen mode Exit fullscreen mode
  • or: Returns True if one of the statements is true. 
  x = (5 > 3 or 5 < 3)   x will be True
Enter fullscreen mode Exit fullscreen mode
  • not: Reverses the result, returns False if the result is true. 
  x = not(5 > 3)   x will be False
Enter fullscreen mode Exit fullscreen mode
  1. Assignment Operators Assignment operators are used to assign values to variables.
  • =: Assigns a value to a variable. 
  x = 5
Enter fullscreen mode Exit fullscreen mode
  • +=: Adds and assigns the result. 
  x += 3   x will be 8 if x was 5
Enter fullscreen mode Exit fullscreen mode
  • -=: Subtracts and assigns the result. 
  x -= 3   x will be 2 if x was 5
Enter fullscreen mode Exit fullscreen mode
  • =: Multiplies and assigns the result. 
  x = 3   x will be 15 if x was 5
Enter fullscreen mode Exit fullscreen mode
  • /=: Divides and assigns the result. 
  x /= 3   x will be 1.6667 if x was 5
Enter fullscreen mode Exit fullscreen mode
  • %=: Takes modulus and assigns the result.

python
  x %= 3   x will be 2 if
