Limitations of Python Ternary Operator
Python ternary operator is used to write concise conditional statements but it too have some limitations.
- Readability: Ternary operator can make simple conditional expressions more concise, it can also reduce the readability of your code, especially if the condition and the expressions are complex.
- Potential for Error: Incorrect placement of parentheses, missing colons, or incorrect order of expressions can lead to syntax errors that might be harder to spot.
- Debugging: When debugging, it might be harder to inspect the values of variables involved in a complex ternary expression.
- Maintenance and Extensibility: Complex ternary expressions might become harder to maintain and extend especially when the codebase grows.
- Can’t use assignment statements: Each operand of the Python ternary operator is an expression, not a statement, that means we can’t use assignment statements inside any of them. Otherwise, the program will throw an error.
Example:
3 if True else x=6
Output:
File "Solution.py", line 1
3 if True else x=6
^
SyntaxError: can't assign to conditional expression
Ternary Operator in Python
In Python, Ternary Operator determines if a condition is true or false and then returns the appropriate value as the result. The ternary operator is useful in cases where we need to assign a value to a variable based on a simple condition, and we want to keep our code more concise — all in just one line of code.
It’s convenient when we want to avoid writing multiple lines for a simple if-else condition. Like in simple if-else, the first option, the true_value will be executed when the condition provided in the expression is True. If the condition returns False, then false_value will be executed.
Syntax: true_value if condition else false_value
The ternary operator can be used in various ways. Let us see a few different examples to use Ternary Operators in Python:
