If you do not like to write manually lists with items into them with python or you want to copy and paste lists in python withou having to put the commas and the apostrophes around each item, you can find different shortcuts. If you have an IDE you can easily find some shortcut to do it, but it will alway get some time to do it. As an alternative you can use this script that creates a GUI with tkinter for python of course.<\/p>\n\n\n\n

import tkinter as tk\n\n\ndef create_list(inpw, outw):\n\tcontent = inpw.get(\"0.0\", tk.END)\n\tcontent = content.splitlines()\n\tfor i in content:\n\t\tif i == \"\":\n\t\t\tindex = content.index(i)\n\t\t\tcontent.pop(i)\n\tprint(content)\n\tcontent = \"mylist = [\" + \",\".join(content) + \"]\"\n\tprint(content)\n\toutw.insert(\"0.0\", content)\n\n# Widgets\nclass Start:\n\tglobal text, text2\n\n\troot = tk.Tk()\n\ttext = tk.Text(root)\n\ttext.pack(side=\"left\")\n\ttext2 = tk.Text(root)\n\ttext2.pack(side=\"left\")\n\troot.bind(\"<Control-b>\",\n\t\tlambda event: create_list(text, text2))\n\troot.mainloop()<\/pre>\n\n\n\n
This is what you get<\/p>\n\n\n\n
\"\"<\/a>
This is the GUI, input something on the left<\/figcaption><\/figure>\n\n\n\n
\"\"<\/a>
Now press ctrl+b<\/figcaption><\/figure>\n\n\n\n
\"\"<\/a>
You will have your list<\/figcaption><\/figure>\n\n\n\n
It is useful when lists are long and you get them from a copy and paste from somewhere like this example here:<\/p>\n\n\n\n
Say we want to make this list of built-in functions in python we get from the page of the documentation<\/p>\n\n\n\n
\"\"<\/a>
Select and copy this functions names<\/figcaption><\/figure>\n\n\n\n
\"\"<\/a>
Now paste them into the app<\/figcaption><\/figure>\n\n\n\n
\"\"<\/a>
Press crtl+b<\/figcaption><\/figure>\n\n\n\n
mylist = [abs(),,delattr(),,hash(),,memoryview(),,set(),,all(),,dict(),,help(),,min(),,setattr(),,any(),,dir(),,hex(),,next(),,slice(),,ascii(),,divmod(),,id(),,object(),,sorted(),,bin(),,enumerate(),,input(),,oct(),,staticmethod(),,bool(),,eval(),,int(),,open(),,str(),,breakpoint(),,exec(),,isinstance(),,ord(),,sum(),,bytearray(),,filter(),,issubclass(),,pow(),,super(),,bytes(),,float(),,iter(),,print(),,tuple(),,callable(),,format(),,len(),,property(),,type(),,chr(),,frozenset(),,list(),,range(),,vars(),,classmethod(),,getattr(),,locals(),,repr(),,zip(),,compile(),,globals(),,map(),,reversed(),,import<\/strong>(),,complex(),,hasattr(),,max(),,round()]<\/p>\n\n\n\n
This is what you get, but we need to make some adjustment.<\/p>\n\n\n\n
import tkinter as tk\n\n\ndef create_list(inpw, outw):\n\tcontent = inpw.get(\"0.0\", tk.END)\n\tcontent = content.splitlines()\n\tprint(content)\n\tfor n, i in enumerate(content):\n\t\tif i == \"\":\n\t\t\tcontent.pop(n)\n\tprint(content)\n\tcontent = \"mylist = [\" + \",\".join(content) + \"]\"\n\tprint(content)\n\toutw.insert(\"0.0\", content)\n\n# Widgets\nclass Start:\n\tglobal text, text2\n\n\troot = tk.Tk()\n\ttext = tk.Text(root)\n\ttext.pack(side=\"left\")\n\ttext2 = tk.Text(root)\n\ttext2.pack(side=\"left\")\n\troot.bind(\"<Control-b>\",\n\t\tlambda event: create_list(text, text2))\n\troot.mainloop()<\/pre>\n\n\n\n
\"\"<\/a>
NOw it’s better, we get rid of the empty lines<\/figcaption><\/figure>\n\n\n\n
import tkinter as tk\n\n\ndef create_list(inpw, outw):\n\tcontent = inpw.get(\"0.0\", tk.END)\n\tcontent = content.splitlines()\n\tprint(content)\n\tfor n, i in enumerate(content):\n\t\tprint(type(i))\n\t\tif i == \"\":\n\t\t\tcontent.pop(n)\n\t\tif type(i) == str:\n\t\t\tcontent[n] == f\"{i}\"\n\tprint(content)\n\tcontent = \"mylist = ['\" + \"','\".join(content) + \"']\"\n\tprint(content)\n\toutw.insert(\"0.0\", content)\n\n# Widgets\nclass Start:\n\tglobal text, text2\n\n\troot = tk.Tk()\n\ttext = tk.Text(root)\n\ttext.pack(side=\"left\")\n\ttext2 = tk.Text(root)\n\ttext2.pack(side=\"left\")\n\troot.bind(\"<Control-b>\",\n\t\tlambda event: create_list(text, text2))\n\troot.mainloop()<\/pre>\n\n\n\n
Now we got also the apostrophes<\/p>\n\n\n\n
\"\"<\/a>
Now I just can copy this into my code<\/figcaption><\/figure>\n\n\n\n
With some little adjustment we could make other shortcuts to make dictionaries too.<\/p>\n\n\n\n
