In Python, and and or are keywords that are reserved character sequences with special functions.
Specifically, and and or are mainly used in conditional statements to concatenate multiple conditions. and play in conditional statementswith ".The function of juxtaposition, the multiple conditions connected by and are true only if they are true at the same time, and the entire condition statement is true, otherwise all false and false. and the or play " in the conditional statementorAs long as one of the multiple conditions connected by or is true, then the entire conditional statement is true, and only if all of them are false, the entire conditional statement is false.
At the same time, in Python programming, conditional statements are often used with if functions to form if statements, as shown in the following examples:
As shown above, the same conditions, different connection methods, the output result is also different. In test two, the num > digit in the condition statement of the if statement is obviously false, but because the previous condition flag is true, and the or is used to connect the two conditions before and after, the whole if condition is also true.
All in alland and or are mainly used in Python programming to write if conditional statementsThe difference is that AND is a false and all false, and OR is a true and all true.
