How do you write 3 if statements in Python?

How do you write 3 if statements in Python?

Example: Python if Statement # If the number is positive, we print an appropriate message num = 3 if num > 0: print(num, “is a positive number.”) print(“This is always printed.”) num = -1 if num > 0: print(num, “is a positive number.”) print(“This is also always printed.”)

What is the syntax of if statement in Python?

Here’s an example: if 51<5: print(“False, statement skipped”) elif 0<5: print(“true, block executed”) elif 0<3: print(“true, but block will not execute”) else: print(“If all fails.”)

Is there an IF function in Python?

Python if Statement is used for decision-making operations. It contains a body of code which runs only when the condition given in the if statement is true. If the condition is false, then the optional else statement runs which contains some code for the else condition.

How do you write multiple If in Python?

If-else conditional statement is used in Python when a situation leads to two conditions and one of them should hold true.

  1. Syntax: if (condition): code1 else: code2 [on_true] if [expression] else [on_false]
  2. Note: For more information, refer to Decision Making in Python (if , if..else, Nested if, if-elif)

What is IF statement and write syntax?

Syntax. In both forms of the if statement, the expressions, which can have any value except a structure, are evaluated, including all side effects. In the first form of the syntax, if expression is true (nonzero), statement is executed. If expression is false, statement is ignored.

How do you write an if statement with two conditions?

You can use logical operators to combine your boolean expressions .

  1. && is a logical and (both conditions need to be true )
  2. || is a logical or (at least one condition needs to be true )
  3. ^ is a xor (exactly one condition needs to be true )
  4. ( == compares objects by identity)

Why do we use == 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 !=

What is == in Python example?

Comparison operators are used to compare values. It returns either True or False according to the condition….Comparison operators.

Operator Meaning Example
== Equal to – True if both operands are equal x == y
!= Not equal to – True if operands are not equal x != y

Why do we use if statements in Python?

In a Python program, the if statement is how you perform this sort of decision-making. It allows for conditional execution of a statement or group of statements based on the value of an expression.

How do you use multiple IF?

To use multiple IF functions where we can add multiple logical tests, after the first logical condition and TRUE value, again insert another IF Function followed by the different logical values to be compared with the TRUE value result.

What does == in code mean?

What does == means in programming languages. In programming languages == sign or double equal sign means we are comparing right side with left side. And this comparison returns true or false. We usually use this comparison inside if condition to do something specific.

Why is == used 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 .
