[Tutor] RAD GUI Development (like Visual Studio/VBA)
Hey guys, Can someone advise on a RAD, drag and drop style graphical form/dialog creator? Akin to VBA or Visual Studio that will work with Python? I currently use the PyCharm IDE, which is fantastic. But I don't have the time or the skill to craft it all by hand.

The difficulty with this question is there are so many GUI toolkits for Python, you first have to figure out which one you want to target. There's Tkinter, which is one of the batteries in the Python "batteries included" concept; however many articles and blogs which talk about what to use instead start with a statement that Tk is ugly, so I presume it must be true if so oft repeated. There is also Qt by way of PyQt (or PySide), Gtk+ (pyGObject), wxPython, PyForms, PyGui, fltk, Kivy, just to rattle off a few - I'm sure there are more. In my limited experience, I know some people were quite happy with using Qt Designer and then generating Python code from the result - there's a tool for that (pyuic?). But last I heard about doing this was years and years ago and the state of the art has probably advanced. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Hi Giulia,
When dealing with unformatted data files, a first quick approach
is to read in using standard python routines to read the file
and then proceed via looping the lines of the file. Here is a
very crude code to deal with your sample
(in what follows represents indentations):
# Say you have named your data file "thefile.dat"
thefilename = "./thefile.dat" # Assign the filename to a variable
# read the whole file
with open(thefilename, 'r') as theFile:
>>> contentfile = theFile.read()
# print(contentfile) # peruse the file content. Find patterns to extract data
# split the file in lines according to the newline character "\n"
templines = []
for line in contentfile.splitlines():
templines.append(line.strip())
#Following the pattern extract the data
thelines = []
for line in templines:
>>>if ':' in line:
>>temp = line.split(":")
>>for i in range(len(temp)):
try:
temp[i] = float(temp[i])
except:
temp[i] = temp[i]
>>print(temp)
>>thelines.append(temp)
>>>elif ',' in line:
>>temp = line.split(",")
>>for i in range(len(temp)):
try:
temp[i] = float(temp[i])
except:
>>>temp[i] = temp[i]
>>print(temp)
>>thelines.append(temp)
>>>else: # not necessary
pass
# print(thelines) # check a few lines
# Improve the code to deal with large files (big data stuff)
# your turn ...
# make a pandas data frame from the data
import pandas as pd
import numpy as np
mypdframe = pd.DataFrame(np.array(thelines))
print(mypdframe)
Hope this set your learning of python not too stressful,
so you could appreciate its power.

You might as well just use readlines()...
Or better still use for on the file itself:
with open(thefilename, 'r') as theFile
for line in theFile:
if ':' in line:
>>> temp = line.split(":")
>>> for i in range(len(temp)):
> try:
> temp[i] = float(temp[i])
> except:
> temp[i] = temp[i]
def makeFloats(sep, line):
temp = line/split(sep)
for i,v in enumerate(temp)
try:
temp[i] = float(v)
except ValueError,TypeError: pass
return temp
if ':' in line: line = makeFloats(':', line)
if(',' in line: line = makeFloats(',', line)
# into pandas next...
Although I'm not totally sure that is what the OP wanted.
What happens about the header lines for example?

There is nothing even close to the VB GUI builder for Python. That's because Python has to cover many GUI frameworks, VB only has to deal with one. Which is why VB is pretty much useless for anything other than Windows... But there are some GUI tools available: - Glade - PyQt/Side? - SpecTcl - Tkinter - Dabo - WxPython (customised for simple DB apps) I've tried all of them and only Dabo worked for me, but Davo wasn't really suitable for my particular project at the time. But YMMV There are some others I haven't tried too - Kivy, Blackadder(??) And if you want to try using Jython or MacPython(?) you can use the native GUI builders for those: - Eclipse/Netbeans (Java) - XDeveloper (MacOS) - I tried this once and it kind of works... -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
