Looping over a list in Python

👻 See our latest reviews to choose the best laptop for Machine Learning and Deep learning tasks!

I have a list with sublists in it. I want to print all the sublists with length equal to 3.

I am doing the following in python:

for x in values[:]:
    if len(x) == 3:
        print(x)

values is the original list. Does the above code print every sublist with length equal to 3 for each value of x? I want to display the sublists where length == 3 only once.

The problem is solved. The problem is with the Eclipse editor. I don"t understand the reason, but it is displaying only half of my list when I run my loop.

Are there any settings I have to change in Eclipse?

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?

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.

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?

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.
