I'm new to python so I have been trying to figure out how to print the following list in the format below. I have tried to get them through indexes but it doesn't seem to work out. 

So I have a list of tuples that I need to print out in the following format:

```
1. A1 to B1
2. C1 to D2 , C1 to B2 

```

This is the following list I have that I need to convert to that format.

```
[['A1', 'B1'], ['C1', 'D2', 'C1', 'B2', 'C1', 'E3', 'C1', 'A3', 'C1', 'F4', 'C1', 'G5', 'C1', 'H6'], ['E1', 'D1', 'E1', 'F2', 'E1', 'D2', 'E1', 'G3', 'E1', 'H4']]

```
