Python Question
replacing an element of a tuple by another element stored in a list in python
I have a list:
replace_by=['a1','b1','c1','d1','e1']
I also have a list of tuples in the type of
main_list=[('a',[]),('b',[]),('c',[]),('d',[]),('e',[])]
My main goal is to replace the first elements of each tuple in the main_list namely a,b,c,d,e by the corresponding elements in the replace_by list namely a1,b1,c1,d1,e1.
I would appreciate if any one could help me with this in a pythonic way! Thanks in advance!!

Tuples cannot be modified in place. However you can easily create a new version,
replace_by=['a1','b1','c1','d1','e1']
main_list=[('a',[]),('b',[]),('c',[]),('d',[]),('e',[])]
new_list = [(replace_by[i],b)for (i,(a,b)) in enumerate(main_list)]
print(new_list)
