Dictionary puzzle of the week:

The objective is to write an expression or function that, given a dictionary in which each value is a list, transpose it so the result is list of dictionaries, where:

The keys of each new dictionary are the same as the keys of the original dictionary
The values of the ith dictionary correspond to the ith elements of the values of the original dictionary

If that doesn't make sense, here's an example:

# Input:

Python Kata by @nhumrich of the Pythondev Slack communtiy.

Write a function that takes in a string, and returns a string with everything inside curly brackets {} removed. Example: hello {world} returns hello {}. Example 2: {hello} {world} returns {} {}

Only submissions that DO NOT use regex will be accepted for taco's

tacos for: 1st, cleanest, shortest, fastest, my choice

nested doesn't count. So { hello {something} there} should return: {}
