Here are five Python regex examples with explanations: 01 Matching a Simple Pattern import re text = "Hello, World!" pattern = r"Hello" result = re.search(pattern, text) if result:     print("Pattern found:", result.group()) Output: Output: Pattern found: Hello This example searches for the pattern "Hello" in the text and prints it when found. 02 Matching Multiple Patterns import re text = "The quick brown fox jumps over the lazy dog." patterns = [r"fox", r"dog"] for pattern in patterns:     if re.search(pattern, text):         print(f"Pattern '{pattern}' found.") Output: Pattern 'fox' found. Pattern 'dog' found. It searches for both "fox" and "dog" patterns in the text and prints when they are found. 03 Matching Any Digit   import re text = "The price of the

How to Use Relational Operators in Python

If you are working with numeric values in Python, you may find it helpful to use comparison operators to compare them. In this article, we'll explore eight different comparison operators that you can use, and provide examples of how each one works. So if you're looking to compare numeric values in Python, read on to learn more!

Sample python program

Assign 23 to a and 11 to b. Then, apply all the comparison operators. The output is self-explanatory. Bookmark this article to refresh when you are in doubt.

Example

a = 23
b = 11
print("Is a greater than b?", a > b) #greater than
print("Is a less than b?", a < b) #less than
print("Is a greater or equal to b?", a >= b) #greater or equal
print("Is a less or equal to b?", a <= b) #less or equal
print("Is a equal to b (option 1)?", a == b) #test for equality
print("Is a equal to b (option 2)?", a is b) #test for equality
print("Is a not equal to b (option 1)?", a != b) #test for inequality
print("Is a not equal to b (option 2)?", a is not b) #test for inequality


The output

Is a greater than b? True
Is a less than b? False
Is a greater or equal to b? True
Is a less or equal to b? False
Is a equal to b (option 1)? False
Is a equal to b (option 2)? False
Is a not equal to b (option 1)? True
Is a not equal to b (option 2)? Tru
