What does end=' ' mean in python

Including end=" as a parameter of print()BIF will cause the function to turn off the default behavior of "automatically including newlines in the output".

The principle is:

is End passes an empty string at the end, so that the print function does not add a newline character to the end of the string, but adds an empty string. In fact, this is also a grammatical requirement, indicating that the statement has not ended. This is only useful for Python3, not Python2 Supported.

Print defaults to printing one line with a newline at the end. end=' ' means no newline at the end, just add a space.
