The regular use of the print() function is to display text either in the command-line or in the interactive interpreter. But the same function can also write into a file or an output stream.
Printing to file
In the example we can open a file with a new filename in write mode then mention that filename in the print function. The value to be written to the file can be passed as arguments into the print function.
Example
Newfile= open("exam_score.txt", "w")
# variables
exam_name = "Degree"
exam_date = "2-Nov"
exam_score = 323
print(exam_name, exam_date, exam_score, file=Newfile , sep = ",")
# close the file
Newfile.close()Output
Running the above code gives us a file named exam_scores.txt with the following content.
Degree,2-Nov,323
Printing to standard output
We can also use print() to print ot the standard output or standard error.
Example
import sys
Newfile= open("exam_score.txt", "w")
# variables
exam_name = "Degree"
exam_date = "2-Nov"
exam_score = 323
print(exam_name, exam_date, exam_score, file=sys.stderr, sep = ",")
# close the file
Newfile.close()Output
Running the above code gives us the following result −
Degree,2-Nov,323
