python - Mechanize HTTP Error 400: Bad Request what am I doing wrong -

-

i'm trying upload file specific webpage mechanize , let process file , download again. got no clue, why page still throwing 400 bad request error. set user-agent, accept headers, redirects, got no idea why isn't working.

my current code:

import mechanize import cookielib cj = cookielib.lwpcookiejar()  br = mechanize.browser() br.addheaders = [('user-agent', 'mozilla/5.0 (x11; u; linux i686; en-us; rv:1.9.0.1) gecko/2008071615 fedora/3.0.1-1.fc9 firefox/3.0.1'),                      ('accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'),                     ('accept-language', 'de,en-us;q=0.7,en;q=0.3'),                      ('accept-encoding', '')] br.set_handle_robots(false) br.set_cookiejar(cj) br.set_handle_equiv(true) br.set_handle_redirect(true) br.set_handle_referer(true) br.set_handle_robots(false) br.set_handle_refresh(mechanize._http.httprefreshprocessor(), max_time=1)             filename = "spinner-metre.png" url = 'http://waifu2x.udp.jp/' br.open(url) br.select_form(nr=0) br.form.add_file(open(filename), 'text/plain', filename) br.form.set_value(['2'],name='noise') br.form.set_value(['2'],name='scale')  br.submit() print br.read()

what doing wrong , how possibly fix this?

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
