What does {:d} do in Python?
So I understand that you can do, for example:
x = input("Enter an integer: ")
print("I am now printing variable x: {}".format(x))
To get the output of whatever string I put in there, as {} is simply the placeholder for the variable.
However, on a website I saw {:d} being used, and despite experimenting in Python to figure out what it does, I cannot seem to find its use. Why is {:d} used when printing the variable and what use does it have?

Please look at the documentation: docs.python.org/3.7/library/string.html It's a format specifier.

For string formatting I prefer to use pyformat.info over the normal docs. For the case of{:d}, which I agree is very hard to search for online, see this section

In python you can specify the format inside the curved brackets.
You can do things such as
>>> '{:b}'.format(2)
'10'
In your case, d prints as decimal integer.
You can find all the doc here
