Is sep a function in Python? How to use it?

sep in Python is not a function, it is a parameter of the print function, used to define the interval symbol between output data.

The specific usage is as follows:

When printing multiple strings at the same time, each string will automatically use spaces as the interval between each string by default.

print("abc", "uuu", "oop")
# abc uuu oop

If you add sep = at the end of multiple strings, you can change the interval. For example, here we change it to no interval.

print("abc", "uuu", "oop", sep = "")
# abcuuuoop

can also be changed to commas as intervals.

print("abc", "uuu", "oop", sep = ", ")
# abc,uuu,oop

Of course special symbols are also acceptable.

print("abc", "uuu", "oop", sep = " & ")
# abc&uuu&oop

If you use \n, it will wrap automatically as usual.

print("abc", "uuu", "oop", sep = " \n")
# abc
# uuu
# oop
