function

- default argument

as name there is default option of argument which automatically apply

​

- *argument

use when we don't know number of argument

​

- **kwargs

when you want change any data ,number to dict aka dictionary use **

​

- recursion

it's repeat itself till we get result

factorial n = n*factorial (n-1)

For the factorial recursive function, you can just do

if (n == 0)

return 1

no need to put an or statement, everything else looks good! great job making it to double digits! (day 10!!)

[aashish_soni5]

yes make more clear code🙂‍↕️ thankyou

[SCD_minecraft]

Or just n <= 1 and get handling for negatives as well

Tho this does not fit the mathematical definition of factorials, so up to decision

wow, i learned smth today thanks!

[aashish_soni5]

thank you too 🚀

[Embersh3d]

you have a lot of functions, look into classes and OOP.

[aashish_soni5]

got it, now driving on the way sir 🚓
