In Python how do I use a for loop, to create nested list from dictionary?

You need to iterate all over fruits keys and build a list repeating the key N=value times.

You can accomplish this with a list comprehension.

• To iterate all over dict items you'll need fruits.items().
• To build a list repeating each key N times do: [key]*N.
• As dict values indicate how many times to repeat, do: [key]*value.

Finally:

fruits_list = [[key]*value for key, value in fruits.items()]

Then print(fruit_list) gives you:
