I was wondering if I can use a simpler method to print("{:<3} {:<30} {:<30}".format(x+1, cam, img)).
I'm using print(f"including a variable named var : {var}") 
instead of print("including a variable named var :{}".format(var))
But with the f"" I can't find a method to put minimal margin unlike "{:<30}".format(var)
Thanks for help !
