Evaluate a complex expression using variables - Python Program

To evaluate a complex expression using variables in Python, you first define the variables and then construct the expression using those variables. Python automatically handles the order of operations (operator precedence) when evaluating the expression.

Steps:

  • Define Variables:Assign values to your variables using the assignment operator (=).

                       x = 10
                       y = 5
                       z = 2

  • Construct the Expression:Write the complex expression using the defined variables and various operators (arithmetic, comparison, logical, etc.).

                      expression = (x + y) * z - (x / y) ** z

  • Evaluate the Expression:Python will automatically evaluate the expression when it is assigned to a new variable or printed.

                     result = expression
                     print(result)

 

# Define variables a = 7 b = 3 c = 4 # Construct a complex expression # This expression demonstrates arithmetic operators, parentheses for grouping, # and exponentiation. complex_expression = (a * b) + (c ** 2) - (a / b) # Evaluate the expression evaluated_result = complex_expression # Print the result print(f"The value of the expression is: {evaluated_result}")

Output

 
OUTPUT  :
The value of the expression is: 34.666666666666664
    

Explanation of the example:

  • a, b, and care assigned integer values.
  • complex_expressionis defined:
    • (a * b)evaluates to 7 * 3 = 21.
    • (c ** 2)evaluates to 4 ** 2 = 16.
    • (a / b)evaluates to 7 / 3 = 2.333....
    • The expression then becomes 21 + 16 - 2.333..., which results in approximately 666....
  • The print()function displays the calculated evaluated_result.
