python - TypeError: 'in <string>' requires string as left operand, not QString -

-

i'm trying write simple app send (and possibly receive) emails gmail account. managed while hardcoding account information in source code, wanted enter them in gui fields , read information there. here code:

import sys import smtplib pyqt4 import qtcore, qtgui notifier_main import ui_notifier_main_gui  class maingui(qtgui.qwidget, ui_notifier_main_gui):     def __init__(self):         qtgui.qwidget.__init__(self)         self.setupui(self)         self.sendbutton.clicked.connect(self.send)      def send(self):         fromaddr = self.senderemaillineedit.text()         toaddrs  = self.receiveremaillineedit.text()         msg = self.msgtextedit.toplaintext()         username = self.senderemaillineedit.text()         server = smtplib.smtp("smtp.gmail.com:587")         server.starttls()         server.login(username, 'password')         server.sendmail(fromaddr, toaddrs, msg)         server.quit()  if __name__ == "__main__":     app = qtgui.qapplication(sys.argv)     main_gui = maingui()     main_gui.show() sys.exit(app.exec_())

when run long ass error:

 c:\python27\python.exe "e:/python projekti/notifier/src/main.py" traceback (most recent call last):   file "e:/python projekti/notifier/src/main.py", line 20, in send     server.sendmail(fromaddr, toaddrs, msg)   file "c:\python27\lib\smtplib.py", line 728, in sendmail     (code, resp) = self.mail(from_addr, esmtp_opts)   file "c:\python27\lib\smtplib.py", line 480, in mail     self.putcmd("mail", "from:%s%s" % (quoteaddr(sender), optionlist))   file "c:\python27\lib\smtplib.py", line 141, in quoteaddr     m = email.utils.parseaddr(addr)[1]   file "c:\python27\lib\email\utils.py", line 214, in parseaddr     addrs = _addresslist(addr).addresslist   file "c:\python27\lib\email\_parseaddr.py", line 457, in __init__     self.addresslist = self.getaddrlist()   file "c:\python27\lib\email\_parseaddr.py", line 218, in getaddrlist     ad = self.getaddress()   file "c:\python27\lib\email\_parseaddr.py", line 228, in getaddress     self.gotonext()   file "c:\python27\lib\email\_parseaddr.py", line 204, in gotonext     if self.field[self.pos] in self.lws + '\n\r': typeerror: 'in <string>' requires string left operand, not qstring

i tried googling type error, , found link spyderlib since i'm pretty new @ this, couldn't figure out that.

most requests qt elements have text return qstrings, simple string container qt uses. other libraries going expect regular python strings, casting using str() may necessary. of:

fromaddr = self.senderemaillineedit.text() toaddrs  = self.receiveremaillineedit.text() msg = self.msgtextedit.toplaintext() username = self.senderemaillineedit.text()

are qstring objects.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
