HTML upload script (example) - don't forget the multipart/form-data encoding type and the max value file size - :

<!DOCTYPE html>
<html lang="en">
<head>
<meta content="text/html; charset=utf-8" http-equiv="content-type" />
<title>Upload Form Page</title>
</head>
<body>
<H2>Upload File</H2><P>
<FORM ENCTYPE="multipart/form-data" METHOD="POST" ACTION="upload.py">
<INPUT TYPE="hidden" NAME="MAX_FILE_SIZE" VALUE="2048">
<INPUT TYPE="file" SIZE="70" NAME="uFile">
<P><INPUT TYPE="SUBMIT" VALUE="upload">
</FORM>
</body>
</html>

Python upload script (example derived from ISBN-13: 978-2744021497 book) :

#!/usr/bin/python
import cgi, os, sys, string
import posixpath, macpath # modify here to fit you os.

## here is the tip for Win32 bin uploads ##
import cgitb; cgitb.enable()
import msvcrt, os
msvcrt.setmode (0, os.O_BINARY)
msvcrt.setmode (1, os.O_BINARY)
############################

saveDir = "../your_directory" # modify your target directory

#Send errors to browser
sys.stderr = sys.stdout

#Parse data from form
data = cgi.FieldStorage()

#Save the file to server directory
def saveFile(uFile):
fPath = "%s/%s" % (saveDir, uFile.filename)
buf = uFile.file.read()
sFile = open(fPath, 'wb')
sFile.write(buf)
sFile.close()

#Send response to brower
webText = """Content-type: text/html\n"
<TITLE>CGI Upload Form</TITLE>\n
<H2>Upload File</H2><P>"""
print webText

if data.has_key('uFile'):
saveFile(data['uFile'])
print "<B>%s</B> uploaded." % (data['uFile'].filename)
