At any rate, if you’re interested in fast solutions, check out the slice, starred expression, copying, and multiplication solutions. Of course, I’d say the built-in copy function is the way to go—regardless of speed.ChallengeNow that we’ve covered several copying mechanisms in Python, ...
# Using slicing to reverse a string my_string = 'Hello, World!' reversed_string = my_string[::-1] print(reversed_string) The [::-1] syntax in the above code tells Python to slice the entire string and step backward by -1, which effectively reverses the string. ...
You already used one of them, the Python interactive interpreter, also known as the read-evaluate-print loop (REPL). Even though the REPL is quite useful for trying out small pieces of code and experimenting, you can’t save your code for later use. To save and reuse your code, you ...
