i follow the python guide to write a html and cgi script as follow in pyCharm on a macbook,however,i got 404 error after i click submit

the html

Output:<html>
<title>Interactive Page</title>
<body>
<form method=POST action="cgi-bin/cgi101.py">
    <P><B>Enter your name:</B>
    <P><input type=text name=user>
    <P><input type=submit>
</form>
</body></html>

the cgi script

#!/usr/bin/python
import cgi
form = cgi.FieldStorage()
print('Content-type: text/html\n')
print('<title>Reply Page</title>')
if not 'user' in form:
    print('<h1>Who are you?</h1>')
else:
    print('<h1>Hello <i>%s,</i>!</h1>' % cgi.escape(form['user'].value))

Could you please share the tutorial link?

What are the permissions for cgi-bin/cgi101.py?
Test it with chmod 755 cgi101.py.

i used pycharm to write the script
so the cgi101.html and cgi101.py are locate in my macbook /Users/xxxxx/PycharmProjects/python/python_program_1/CGI
tried chmod 755 cgi101.py,still got the 404 error

Which Web Server are you using?
It must support CGI and you'll have to put all the files in its folder (/var/www ?).

no,i put it in /Library/Webserver/GCI-Executables
i follow this link to write a new script
but the when i open
[url=http://localhost/cgi-bin/test.py]http://localhost/cgi-bin/test.py
,it gives the text,not the result of python script.
so why the script does not run?
if this issue can be solved,i think i can solve my original.

Ok, lets investigate the error following this last tutorial.

Post the output of these commands:
1 - ls -la /Library/Webserver/GCI-Executables
2 - ls -la /var/log/apache2
2.1 - cat /var/log/apache2/error_log

It seems to be something with the apache.
Lets see some more info:

3 - cat /var/log/apache2/access
4 - cat /etc/apache2/httpd.conf
5 - ls -la /etc/apache2/users/

If there is a user config file in 5, post its content too.
5.1 - ls -la /etc/apache2/users/some_user.config

Did you restart the apache server?

sudo apachectl restart
