Functions within Functions: Callback Functions

A callback function is a function that is passed as a parameter to another function and is invoked within that function.

Callbacks are useful when you want to execute additional actions when certain conditions are met or when you need to process follow-up tasks after data is ready.


How to Use Callback Functions?

Callback functions are passed as parameters to other functions, which then call them to execute various operations dynamically.

Callback Function Example
# Define callback functions def add_one(number): return number + 1 def multiply_by_two(number): return number * 2 # Function that accepts a callback function as an argument def process_number(number, callback): result = callback(number) print(f"Processed Result: {result}") # Process with add_one function, prints 11 process_number(10, add_one) # Process with multiply_by_two function, prints 20 process_number(10, multiply_by_two)
