Write a context-free grammar in the form of BNF notation to satisfy the following requirements, Write a grammar for the "for" statement in Python. The grammar should only satisfy the following examples. In Python "for" loops can be written in many other forms. We do not intend to satisfy the forms which their examples are not presented here. In example 1, "i" is a variable and the list [45, 6, 7, 78] can have any number of members. Members of the list can only be numbers. In example 2, "key" and "value" are variables separated by commas, and the list [(11,12), (3,4), (5,7)] is a list of tuples. Variables only consist of alphabet characters.
