Can Python write on one line?

Summary: To make a Python one-liner out of any multi-line Python script, replace the new lines with a new line character ‘\n’ and pass the result into the exec(…) function. You can run this script from the outside (command line, shell, terminal) by using the command python -c “exec(…)” .

How do I make one-liner in Python?

How to Write a For Loop in a Single Line of Python Code?

1. If the loop body consists of one statement, simply write this statement into the same line: for i in range(10): print(i) .
2. If the purpose of the loop is to create a list, use list comprehension instead: squares = [i**2 for i in range(10)] .

Which character is used in Python to make a single line command?

In Python, we use the hash symbol # to write a single-line comment.

How do you write if-else in one line in Python?

One Line If-Else Statements in Python Writing a one-line if-else statement in Python is possible by using the ternary operator, also known as the conditional expression. This works just fine. But you can get the job done by writing the if-else statement as a neat one-liner expression.

What do semicolons do in Python?

A semi-colon in Python denotes separation, rather than termination. It allows you to write multiple statements on the same line. This syntax also makes it legal to put a semicolon at the end of a single statement: print(‘Why God?

Can multiple Python statements be written on a single line?

What does First () do in Python?

first is an MIT-licensed Python package with a simple function that returns the first true value from an iterable, or None if there is none.

What is the best way to write one-liners in Python?

The most naive way of doing this is: However, Python provides one-liner for this also. The Pythonic way is: One-Liner #4 Lambda Functions (Anonymous Functions) – Lambda functions are python one liner functions and are often used when an expression is to be evaluated.

Can python do a lot with a little with one line?

Python one-liners can be just as powerful as a long and tedious program written in another language designed to do the same thing. In other languages (think: Java) this would be nearly impossible, but in Python, it’s a lot easier to do. The trick is to think of something that will “do a lot with a little.”

Are your one-liner tricks pythonic or unpythonic?

As a rule of thumb: if you use one-liners that are confusing, difficult to understand, or to show off your skills, they tend to be Unpythonic. However, if you use well-established one-liner tricks such as list comprehension or the ternary operator, they tend to be Pythonic. So, use your one-liner superpower wisely!

What do you like most about Python?

The ability to write short programs that are just as powerful as a program written in another language designed to do the same thing. However, it is sometimes fun to try and write a program in Python that is only one line. In other languages this would be nearly impossible, but in Python it is a lot easier to do.
