- My post explains range().

- My post explains iterable unpacking in variable assignment.
- My post explains
*for iterable unpacking in variable assignment. - My post explains
[]and()for variables in variable assignment. - My post explains
[]and()for variables inforstatement.
zip() can create the iterable which has zero or more iterables as shown below:
*Memos:
- The 1st or more arguments are
*iterables(Optional-Type:iterable). *Don't use any keywords like*iterables=,iterables=,iterable=, etc. - The iterable stops when the shortest input iterable is exhausted.
- The iterable cannot be directly accessed with index so use list() to access it with index.
