Short Recap – Creating a Program

An arbitrary editor (nano, idle3, gedit, vim, ...) can be used to create the program code and save it as a file

$ ssh -Y <username>@rackham.uppmax.uu.se

Open editor, e.g., vi:
```
$ vi product.py
```
Load module:
```
$ module load python/3.9.5
```
Then you can run your program in the terminal window:
```
$ python3 product.py
```
Note: We count from 0!

A = "ACGTCGA"
print(len(A))
for i in range(len(A)):
    print(i, A[i])
