How do I print to stderr in Python?
In Python, you can use the print()
function to print to stderr
by passing the value file=sys.stderr
as a keyword argument. For example:
import sys
print("This is an error message", file=sys.stderr)
This will print the string "This is an error message" to the standard error stream.
Alternatively, you can use the sys.stderr.write()
method to write a string to the standard error stream:
import sys
sys.stderr.write("This is an error message\n")
This will have the same effect as the print()
function above.
