Slicing Strings
Info:
You can return a range of characters by using the slice syntax.
To use this, specify the start and the end index, separated by a colon, to return a part of the string.
Example:
The example below, will get the characters from the position 2 to position 5 (position 5 is not included)
b = "Hello, World!"
print(b[2:5])
And the code above will give the following output:
llo
Note that the chosen end index is not included in the print. So when you choose a range to slice, it always includes the beginning but not the ending.
What if you want to slice from the start?
By leaving out the start index, the range will start at the first character.
b = "Hello, World!"
print([:5])
As you can see above, the beginning part of the index is not written, so this means that it starts from the beginning. You can do the same thing for the end of the string as well such as:
b = "Hello, World"
print([2:])
And in this case, the print will start from the third character (index 2) and will end at the end of the string.
You can also use negative indexing to start the slice from the end of the line. Here's an example:
b = "Think Different"
print(b[-5:-2])
And the output of the above code will be:
