How do I copy a string to the clipboard? By Dancrew32

I"m trying to make a basic Windows application that builds a string out of user input and then adds it to the clipboard. How do I copy a string to the clipboard using Python?

215

Actually, `pywin32` and `ctypes` seem to be an overkill for this simple task. `Tkinter` is a cross-platform GUI framework, which ships with Python by default and has clipboard accessing methods along with other cool stuff.

If all you need is to put some text to system clipboard, this will do it:

``````from Tkinter import Tk
r = Tk()
r.withdraw()
r.clipboard_clear()
r.clipboard_append("i can has clipboardz?")
r.update() # now it stays on the clipboard after the window is closed
r.destroy()
``````

And that"s all, no need to mess around with platform-specific third-party libraries.

If you are using Python 3, replace `TKinter` with `tkinter`.

Python script to copy text to clipboard

I just need a python script that copies text to the clipboard.

After the script gets executed i need the output of the text to be pasted to another source. Is it possible to write a python script that does this job?

194

See Pyperclip. Example (taken from Pyperclip site):

``````import pyperclip
pyperclip.copy("The text to be copied to the clipboard.")
spam = pyperclip.paste()
``````

Also, see Xerox. But it appears to have more dependencies.

InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately

Tried to perform REST GET through python requests with the following code and I got error.

Code snip:

``````import requests
url = az_base_url + az_subscription_id + "/resourcegroups/Default-Networking/resources?" + az_api_version
``````

Error:

``````/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/util/ssl_.py:79:
InsecurePlatformWarning: A true SSLContext object is not available.
This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.
InsecurePlatformWarning
``````

My python version is 2.7.3. I tried to install urllib3 and requests[security] as some other thread suggests, I still got the same error.

Wonder if anyone can provide some tips?

334

The docs give a fair indicator of what"s required., however `requests` allow us to skip a few steps:

You only need to install the `security` package extras (thanks @admdrew for pointing it out)

``````\$ pip install requests[security]
``````

or, install them directly:

``````\$ pip install pyopenssl ndg-httpsclient pyasn1
``````

Requests will then automatically inject `pyopenssl` into `urllib3`

If you"re on ubuntu, you may run into trouble installing `pyopenssl`, you"ll need these dependencies:

``````\$ apt-get install libffi-dev libssl-dev
``````

Dynamic instantiation from string name of a class in dynamically imported module?

In python, I have to instantiate certain class, knowing its name in a string, but this class "lives" in a dynamically imported module. An example follows:

``````import sys
def __init__(self, module_name, class_name): # both args are strings
try:
__import__(module_name)
modul = sys.modules[module_name]
instance = modul.class_name() # obviously this doesn"t works, here is my main problem!
except ImportError:
# manage import error
``````

``````class myName:
# etc...
``````

I use this arrangement to make any dynamically-loaded-module to be used by the loader-class following certain predefined behaviours in the dyn-loaded-modules...

222

You can use getattr

``````getattr(module, class_name)
``````

to access the class. More complete code:

``````module = __import__(module_name)
class_ = getattr(module, class_name)
instance = class_()
``````

As mentioned below, we may use importlib

``````import importlib
module = importlib.import_module(module_name)
class_ = getattr(module, class_name)
instance = class_()
``````

How to get all of the immediate subdirectories in Python

I"m trying to write a simple Python script that will copy a index.tpl to index.html in all of the subdirectories (with a few exceptions).

I"m getting bogged down by trying to get the list of subdirectories.

184

``````import os
def get_immediate_subdirectories(a_dir):
return [name for name in os.listdir(a_dir)
if os.path.isdir(os.path.join(a_dir, name))]
``````
