Data Types in Python

Compare StringsCompare Strings

This chapter encompasses two distinct subjects: strings and boolean statements. The syntax we will cover here can prove quite valuable and significantly reduce the complexity of your code.

As I previously mentioned, operators such as >, <, ==, >=, and <= can be quite efficient. Now, let's explore how they can be applied to strings.

Let's start with the simplest one: ==. This compares two statements and returns True if they are equal the same way with strings:

In the first case, the names are different, but in the second they are completely equal. It's not a piece of brand-new information; therefore, let's move on to the other signs. As you may recall, X > Y means that X is greater than Y. But what can we say about the following operation?

The expression means True because B is greater than A, but how can string be greater?

Note

There is a singular method for comparing letters according to their alphabetical order. This implies that within the alphabet, the letter B is considered greater than A as it is positioned further along. To organize items alphabetically or to perform personal assessments, you can utilize the > and < symbols.

By the way, we can compare even words. The algorithm of comparing is the following: It compares words by the first letters that differ:

Explanation: The first two letters are equal, so comparing starts from the third letter in each word (the first unequivalent letter).

Task

To achieve resounding success you need to practice. 🤓 Your task here is to put the > or < sign to receive a True or False statement ( hint, the alphabet was attached):

  1. False in the first statement
  2. False in the second statement
  3. True in the third statement

Everything was clear?
