How do I print to stderr in Python?

To print to stderr in Python, you can use the stderr attribute of the sys module:

import sys

sys.stderr.write("This is an error message\n")

Alternatively, you can use the print() function with the file argument set to sys.stderr:

import sys

print("This is an error message", file=sys.stderr)

Both of these methods will print the specified message to the stderr stream.
