GUI list of installed packages

[Larz60+]

Hello,

I had this posted on python-forum.org.
It's a simple tkinter list of installed packages and version numbers

import tkinter.tix as tk
import tkinter.filedialog as tf
import pip


class GetPackages:
    def __init__(self, parent):
        self.w = parent
        self.bgc1 = '#ffffe5'
        self.bgc2 = 'Lavender'
        self.bgc3 = ' LightCyan'
        self.pkglist = None
        self.w.geometry('400x400+10+10')
        self.w.title("Larz60+ Python Package List")
        self.process_data()

    def get_pkgs_from_pip(self):
        self.pkglist = pip.get_installed_distributions()

    def process_data(self):
        w = self.w

        # Get Package list
        self.get_pkgs_from_pip()

        t1 = tk.Text(w, wrap=tk.WORD, undo=0, bg=self.bgc1)
        t1.pack(expand=1, fill=tk.BOTH)
        t1scroll = tk.Scrollbar(t1)
        t1.configure(yscrollcommand=t1scroll.set)
        t1scroll.config(command=t1.yview)
        t1scroll.pack(side=tk.RIGHT, fill=tk.Y)
        b1 = tk.Button(w, text='Save', command=self.save_results)
        b1.pack(side=tk.BOTTOM)

        t1.insert(tk.END, "{Package Name} -- {Version Info}\n\n")
        for item in self.pkglist:
            t1.insert(tk.END, "   {} -- {}\n".format(item.key, item.version))

    def save_results(self):
        filename = tf.asksaveasfilename()
        with open(filename, 'w') as f:
            for item in self.pkglist:
                f.write('{},{}\n'.format(item.key, item.version))

if __name__ == '__main__':
    root = tk.Tk()
    GetPackages(root)
    root.mainloop()
