Function Calls
A function call is when a program executes a subroutine or method from another part of the program. This allows you to reuse code and reduce the need to write repetitive code blocks.
Example:
python
def sum(a, b):
return a + b
result = sum(5, 10)
print(result)
Explanation:
Function Definition: We define a function named sum that takes two arguments, a and b.
Subroutine Call: When we call the function sum with the arguments 5 and 10, we pass them to the sum function.
Execution: The sum function executes its code and returns the sum of the two arguments.
Variable Assignment: The result of the function call is stored in the variable result.
Printing Result: We then print the value of result to the console.
Benefits of Function Calls:
Code Reusability: You can reuse the function in different parts of your program.
Reduced Code Duplication: Function calls eliminate the need to write repetitive code blocks.
Enhanced Maintainability: Functions make it easier to maintain your code, as changes are reflected in all parts that use them.
Additional Notes:
Function calls can be nested, where one function calls another function.
Functions can return values, which can be used in other parts of your program.
Functions can be called from other modules or files
