if test expression: statement(s) As depicted by the flowchart above, the Python program first evaluates the test expression. It is basically the condition in the if statement in Python. If the condition is met or if the condition is true, then only the statement(s) in the body of the ...

The equality operator (==) tests if two variables have an equal value. Given variable x=3 and y=3, we can test for equality using the statement if x == y, which will return true. If we change either x or y, it would return false. It looks like the assignment operator (=) , b...
We can use an if statement to compare the two dates: if datetime1 > datetime2: print(“datetime1 is Greater") if datetime2 > datetime1: print(“datetime2 is Greater") The above code should output “datetime2 is Greater” Now that we know that datetime2 is greater, meaning it came af...

It’s particularly useful in the context of a conditional statement. To illustrate, the example below shows a toy function that checks the length of a string object: Python >>> def validate_length(string): ... if (n := len(string)) < 8: ... print(f"Length {n} is too short...
... assert isinstance(word, basestring), "argument to tag() must be a string" ... if word in ['a', 'the', 'all']: ... return 'det' ... else: ... return 'noun' If the assert statement fails, it will produce an error that cannot be ignored, since it halts program executio...
