How to make a list of the file in a dir with Python

Python 3: for the list of files in the current work directory
>>> import os
>>> for file in os.listdir():
...     print(file)
to include them in a list, just:
x = [f for f in os.listdir()]
If you want to have the list of a particular directory, not the directory where the terminal (or cmd) is:
>>> files = os.listdir('G:/python')
>>> for file in files:
        print(file)

>>> x = [f for f in os.listdir('G:/python')]

Python 2 works differently...
>>> import os
>>> for f in os.listdir(os.getcwd):
...     print f

>>> # create a list
>>> x = [f for f in os.listdir(os.getcwd())] # the current dir
The code above will print all the files in the current directory The same here:
>>> import os
>>> for f in os.listdir('.'):
...     print f

>>> # create a list
>>> x = [f for f in os.listdir('.')] # the current dir
To go up in the directory tree, you got to code like this:
>>> for f in os.listdir(..):
...     print f


>>> # create a list
>>> x = [f for f in os.listdir('..')] # the precedent dir
and this...
>>> for f in os.listdir('/'):
...    print f

>>> # create a list
>>> x = [f for f in os.listdir('/')] # the root dir
... this will print all the files in the root directory
>>> x = [f for f in os.listdir('F:/python')] # a dir...

Widgets for Jupyter Notebook: a text input widget

Widgets for Jupyter notebook ¶ Let's import the module ipywidgets into the Jupyter Notebook from ipywidgets import widgets from ipywidgets import * from traitlets import * Now we import the display function from IPython ¶ let's attach a function to the event on_submit After we run this cell, we can go up and write something in the text widget and after you submit the text you wrote will be printed after the cell from IPython.display import display text = widgets . Text () display ( text ) def handle_submit ( sender ): print ( "Thank you for entering this text:" , text . value ) text . on_submit ( handle_submit ) Thank you for entering this text: Ciao

Image in Jupyter and PIL step by step

Hi, """ Hi, we will see a step by step tutorial about PIL and IPython.core.display modules to create images from other images and diplaying them in Jupyter notebook """ # What we will do # Create a card # 1. Take a pic of a heart # 2. Create an image blanck the size of a card 90*130 # 3. Paste the heart in the middle # 4. show the card """ As first step wi will simply display an image on the notebook. I will show two way to display the image with 'display' from IPhyton a. Using the open method of PIL.Image (named Img) b. Using the Image method from the IPython.core.display module """ # 1. Take the pic of a heart from IPython.core.display import Image , display from PIL import Image as Img heart = 'img/heart.png' display ( Image ( heart )) display ( Img . open ( heart )) # 2. Create an image blanck the size of a card 90*130 # 3. Paste the heart in the middle #...

Let's draw a circle with PIL in Python

Let's continue making our coding around PIL. Let's start with some basic drawing: a circle from PIL import Image , ImageDraw img = Image . new ( "RGB" ,( 60 , 60 ), 'white' ) dr = ImageDraw . Draw ( img ) dr . ellipse (( 0 , 0 , 60 , 60 ), 'yellow' ) img . show () this is the image produced *If you use jupyter notebook, just write img at the end to see the output.
