python shell for nested for

Nested for loops, a dance of iteration,
A loop within a loop, a nested creation.
Indentation is key, for the inner loop’s place,
Keep it concise, for clarity and grace.

Nested for loops in Python allow for the iteration of multiple sequences within each other. This means that you can have a for loop within another for loop, creating a nested structure. This is useful for iterating through 2D arrays, matrices, and other multi-dimensional data structures. It’s important to keep track of the indentation when using nested for loops, as the inner loop should be indented within the outer loop. Additionally, nesting too many for loops can lead to complexity and decreased readability, so it’s important to use nested for loops judiciously.
