Speed Up Python Print Function Performance

In Python, there are several ways to improve the printing speed of the print function.

1. Print on the standard output.
2. output the text on the screen
3. Would you like me to write it?
4. print()

import sys
sys.stdout.write('Hello, World!')

1. Store the content to be printed in a string before outputting it all at once: When there is a need to frequently output a large amount of content, it is advisable to first store the output content in a string and then output it all at once to reduce the number of IO operations.

output = ''
for i in range(1000):
    output += str(i) + ' '
print(output)

1. using multiple processes

import multiprocessing

def print_func(content):
    print(content)

if __name__ == '__main__':
    pool = multiprocessing.Pool()
    pool.map(print_func, ['Hello', 'World'])

By using the methods mentioned above, the printing speed of the print function can be improved, but it is necessary to choose the appropriate method based on the specific situation to optimize program performance.
