find the range of all keys in a map in python

To find the range of all keys in a map (dictionary) in Python, we can use the built-in max() and min() functions. Here is an example code to demonstrate how to do this:

main.py
my_map = {'a': 1, 'b': 2, 'c': 3, 'd': 4}
key_range = range(min(my_map.keys()), max(my_map.keys()) + 1)
print(key_range)
121 chars
4 lines

In the above example, we first create a map (dictionary) my_map with some key-value pairs. We then use the min() and max() functions on the keys() of the dictionary to find the minimum and maximum keys present in the dictionary. The range() function is used to create a sequence of all keys in the dictionary. Finally, we print the key_range sequence which contains all the keys in the dictionary.

Note that the range() function creates a sequence of integers from the start value to end value (inclusive). Therefore, we have added 1 to the maximum key value to ensure that the last key is included in the sequence.
