You should never test a boolean variable with == True (or == False). Instead, either write: if not (var1 or var2 or var3 or var4): or use any (and in related problems its cousin all): if not any((var1, var2, var3, var4)): or use Python's transitive comparisons: if var1 == var2 == var3 == var4 == False:
Python's if statements test multiple conditions with and and or. Those logical operators combine several conditions into a single True or False value.
In Python if-else statements, we can use multiple conditions which can be used with logical and and or operators. Let’s take a look at how we can write multiple conditions into a Python if-else statement: # Using Multiple Conditons in Python if-else . val1 = 2 . val2 = 10 if val1 % 2 == 0 and val2 % 5 == 0: print ("Divisible by 2 and 5.")
These examples illustrate how to handle multiple conditions and variables in if statements, as well as how to use multiple if statements in Python.
To test multiple variables against a single value: Wrap the variables in a set object, e.g. {a, b, c}. Use the in operator to test if the value is stored in any of the variables. The in operator will return True if the value is stored in at least one of the variables.
Use the boolean `and` operator to check for multiple conditions in an if statement in Python.
In Python, if statements are a starting point to implement a condition. Let’s look at the simplest example: if <condition>: <expression> When <condition> is evaluated by Python, it’ll become either True or False (Booleans).
If we want to join two or more conditions in the same if statement, we need a logical operator. There are three possible logical operators in Python: and – Returns True if both statements are true. or – Returns True if at least one of the statements is true.
In this step-by-step tutorial you'll learn how to work with conditional ("if") statements in Python. Master if-statements and see how to write complex decision making code in your programs. Start Here
To combine multiple conditions in an if statement using logical AND or OR, employ the and or or operators, respectively. def if_and ( n ): if n > 0 and n % 2 == 0 : print ( f ' { n } is positive-even' ) else : print ( f ' { n } is not positive-even' ) if_and ( 10 ) # 10 is positive-even if_and ( 5 ) # 5 is not positive-even if_and ( - 10 ...
