How do i do an if statement in python?
Python If ... ElsePython Conditions and If statementsPython supports the usual logical conditions from mathematics: Show
These conditions can be used in several ways, most commonly in "if statements" and loops. An "if statement" is written by using the if keyword. ExampleIf statement: a = 33 Try it Yourself » In this example we use two variables, a and b, which are used as part of the if statement to test whether b is greater than a. As a is 33, and b is 200, we know that 200 is greater than 33, and so we print to screen that "b is greater than a". IndentationPython relies on indentation (whitespace at the beginning of a line) to define scope in the code. Other programming languages often use curly-brackets for this purpose. ExampleIf statement, without indentation (will raise an error): a = 33 Try it Yourself » ElifThe elif keyword is pythons way of saying "if the previous conditions were not true, then try this condition". Example a = 33 Try it Yourself » In this example a is equal to b, so the first condition is not true, but the elif condition is true, so we print to screen that "a and b are equal". ElseThe else keyword catches anything which isn't caught by the preceding conditions. Example a = 200 Try it Yourself » In this example a is greater than b, so the first condition is not true, also the elif condition is not true, so we go to the else condition and print to screen that "a is greater than b". You can also have an Example a = 200 Try it Yourself » Short Hand IfIf you have only one statement to execute, you can put it on the same line as the if statement. ExampleOne line if statement: if a > b: print("a is greater than b") Try it Yourself » Short Hand If ... ElseIf you have only one statement to execute, one for if, and one for else, you can put it all on the same line: ExampleOne line if else statement: a = 2 Try it Yourself » This technique is known as Ternary Operators, or Conditional Expressions. You can also have multiple else statements on the same line: ExampleOne line if else statement, with 3 conditions: a = 330 Try it Yourself » AndThe and keyword is a logical operator, and is used to combine conditional statements: ExampleTest if a = 200 Try it Yourself » OrThe ExampleTest if a = 200 Try it Yourself » Nested IfYou can have Examplex = 41 if x > 10: Try it Yourself » The pass Statement
How do you write an if statement in Python?An "if statement" is written by using the if keyword.. Equals: a == b.. Not Equals: a != b.. Less than: a < b.. Less than or equal to: a <= b.. Greater than: a > b.. Greater than or equal to: a >= b.. How do if statements work in Python?Python if statement evaluates a boolean expression to true or false, if the condition is true then the statement inside the if block will be executed in case if the condition is false then the statement present inside the else block will be executed only if you have written the else block otherwise it will do nothing.
How do you start an if statement?So an IF statement can have two results. The first result is if your comparison is True, the second if your comparison is False. For example, =IF(C2=”Yes”,1,2) says IF(C2 = Yes, then return a 1, otherwise return a 2).
What is == in Python?The == operator compares the value or equality of two objects, whereas the Python is operator checks whether two variables point to the same object in memory. In the vast majority of cases, this means you should use the equality operators == and != , except when you're comparing to None .
