Thus, it slices the year and day part of each date in the list and prints it using‘print(f”Year: {year}, Day: {day}”)’. This is how you can perform slicing in Python string using the slice() function. Conclusion In this Python tutorial, you learned how to dostring slicing in ...
We can also call out a range of characters from the string. Say we would like to only print the wordShark. We can do so by creating aslice, which is a sequence of characters within an original string. With slices, we can call multiple character values by creating a range of index numb...
