What does the percentage mark mean


Hey all, I just wonder shortly what the percentage (%) i wrote in bold text does.

Why does it need to be one after all the others outside the apostrophe

edit: i could not write it in bold text but it is withing 2 stars

print '%s/%s/%s %s:%s:%s' **%** (now.month, now.day, now.year, now.hour, now.minute, now.second)


@mrfatdog21: Found an interesting explanation about it, here's part of it.

Hope it helps you! :slight_smile:

Note: the order you give on that sequence of elements within the parentheses will tell your program at which position a given value should be replaced. Try to switch positions within them and see the result.



That is not the sole way to format string, you have that form and the following,

Python Code:

a_string = 'String Me!'
a_number = 51
a_float = 3.141592653589793

print("{}: {}: {:.2f}".format(a_string, a_number, a_float))
# OUTPUT: String Me!: 51: 3.14

There are some more advanced features you can do, just google string formatting and you will find tons of info on it. (Docs)

Best of luck!

As a side note, you can also use string formatting and some special methods of print to center text and all types of things.

Python Center:

print("{}: {}: {:.2f}".format(a_string, a_number, a_float).center(50))
# OUTPUT:                String Me!: 51: 3.14


@zeziba: I believe that, according to what mrfatdog21 asked, the explanation about % in string formatting should be enough to answer his questions.
Of course there are more ways to do it but I believe it would be more simple to simply show that one but thanks for the reminder.
