You can also use negative index numbers to slice a string. As we went through before, negative index numbers of a string start at -1, and count down from there until we reach the beginning of the string. When using negative index numbers, we’ll start with the lower number first as it...
Suppose you want to extract or slice the string part‘I live’. First, you need to count the number of characters, including space (consider space a character), in the part you want to extract; it contains 6 characters. One thing to remember is that slicing starts from index 0, which ...

There is no built-in function to reverse a String in Python. The fastest (and easiest?) way is to use a slice that steps backwards,-1. ExampleGet your own Python Server Reverse the string "Hello World": txt ="Hello World"[::-1] ...
# 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. Reversing a String Us...
Python does not have a character data type, a single character is simply a string of length1. 2. Substring or Slicing We can get a range of characters by using the slice syntax. Indexes start from0. For example,str[m:n]returns a string from position 2 (including) to 5 (excluding)....
Today, we’ll be looking at how to capitalize a string in Python. There are a few built-in functions for this problem, but we can also roll our own solution.In short, the capitalize() method exists for this purpose. That said, if you need something a bit different than what this ...

In my opinion, this is the most readable option, and I believe it’s also the most efficient version. In fact, the performance should be similar to the slice. However, Python changes a lot, so the other methods mentioned here may be just as performant—check out my benchmarks below ...
