What we have learnt
- Functions in Python can have default values for arguments.
- Function definitions can be conditionally assigned and can be reassigned to different bodies.
- Functions can be passed around as first-class objects, allowing for higher-order functions.
Key Concepts
- -- Default Arguments
- Arguments that assume a default value if not provided during function calls.
- -- Function Reassignment
- The ability to redefine a function to point to a new body of code.
- -- HigherOrder Functions
- Functions that can take other functions as arguments or return them as results.
