How do you use one line on an if statement?
Only use single-line if statements on a single line While the compiler sees this as one statement guarded by a single condition, humans often accidentally read this is an if block, whether there are curly braces or not, thanks to the indentation. Humans notice the indentation, the compiler does not.
Can we write if-else in one line?
Other programming languages like C++ and Java have ternary operators, which are useful to make decision making in a single line. Python does not have a ternary operator. But in python, we can use the if-else in a single line, and it will give the same effect as the ternary operator.
How do you write if-else in one line in Python?
Python if.. elif..else in one line
- First of all condition2 is evaluated, if return True then expr2 is returned.
- If condition2 returns False then condition1 is evaluated, if return True then expr1 is returned.
- If condition1 also returns False then else is executed and expr is returned.
- “If” statements: where if a condition is true it is used to specify execution for a block of code.
- “Else” statements: where if the same condition is false it specifies the execution for a block of code.
- “Else if” statements: this specifies a new test if the first condition is false.
What is single line statement?
The most common usage is to make a terse, simple dependent assignment statement. In other words, it offers a one-line code to evaluate the first expression if the condition is true; otherwise, it considers the second expression.

What is ternary operator in Java?
Java ternary operator is the only conditional operator that takes three operands. It’s a one-liner replacement for the if-then-else statement and is used a lot in Java programming. We can use the ternary operator in place of if-else conditions or even switch conditions using nested ternary operators.
- Use if to specify a block of code to be executed, if a specified condition is true.
- Use else to specify a block of code to be executed, if the same condition is false.
- Use else if to specify a new condition to test, if the first condition is false.
