Everybody knows the print function in Python. It prints a string to the shell–and makes the computation of a Python program explicit to the programmer. But only few coders understand its powerful arguments to format the output. What are they?
There are two little-used arguments of the print function in Python. The argument
sep indicates the separator which is printed between the objects. The argument
end defines what comes at the end of each line.
Consider the following example:
a = 'hello' b = 'world' print(a, b, sep=' Python ', end='!')
Try it yourself in our interactive code shell:
Click “Run” to execute the shell and see the output. What has changed?
The print function has several arguments you can use to format the output.
sep indicates the separator which is printed between the objects. By default
sep is empty space. In the puzzle we set it to be ‘ Python ‘.
end defines what comes at the end of each line. By default
end is a line break. In the puzzle we set it to
'!'. This means that print would print everything in one single line because there is no line break.
When we call
print() with the given arguments and objects a and b we get the output
'hello Python world!'.
Where to Go From Here?
Enough theory, let’s get some practice!
To become successful in coding, you need to get out there and solve real problems for real people. That’s how you can become a six-figure earner easily. And that’s how you polish the skills you really need in practice. After all, what’s the use of learning theory that nobody ever needs?
Practice projects is how you sharpen your saw in coding!
Do you want to become a code master by focusing on practical code projects that actually earn you money and solve problems for people?
Then become a Python freelance developer! It’s the best way of approaching the task of improving your Python skills—even if you are a complete beginner.
