    How can I make a time delay in Python?

    5 answers

    I would like to know how to put a time delay in a Python script.

    2973

    Answer #1

    import time
    time.sleep(5)   # Delays for 5 seconds. You can also use a float value.
    

    Here is another example where something is run approximately once a minute:

    import time
    while True:
        print("This prints once a minute.")
        time.sleep(60) # Delay for 1 minute (60 seconds).
    

    2973

    Answer #2

    You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

    from time import sleep
    sleep(0.1) # Time in seconds

    Javascript Book around: Questions

    Removing white space around a saved image in matplotlib

    2 answers

    I need to take an image and save it after some process. The figure looks fine when I display it, but after saving the figure, I got some white space around the saved image. I have tried the "tight" option for savefig method, did not work either. The code:

      import matplotlib.image as mpimg
      import matplotlib.pyplot as plt
    
      fig = plt.figure(1)
      img = mpimg.imread(path)
      plt.imshow(img)
      ax=fig.add_subplot(1,1,1)
    
      extent = ax.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
      plt.savefig("1.png", bbox_inches=extent)
    
      plt.axis("off") 
      plt.show()
    

    I am trying to draw a basic graph by using NetworkX on a figure and save it. I realized that without a graph it works, but when added a graph I get white space around the saved image;

    import matplotlib.image as mpimg
    import matplotlib.pyplot as plt
    import networkx as nx
    
    G = nx.Graph()
    G.add_node(1)
    G.add_node(2)
    G.add_node(3)
    G.add_edge(1,3)
    G.add_edge(1,2)
    pos = {1:[100,120], 2:[200,300], 3:[50,75]}
    
    fig = plt.figure(1)
    img = mpimg.imread("image.jpg")
    plt.imshow(img)
    ax=fig.add_subplot(1,1,1)
    
    nx.draw(G, pos=pos)
    
    extent = ax.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
    plt.savefig("1.png", bbox_inches = extent)
    
    plt.axis("off") 
    plt.show()
    
    228

    Answer #1

    You can remove the white space padding by setting bbox_inches="tight" in savefig:

    plt.savefig("test.png",bbox_inches="tight")
    

    You"ll have to put the argument to bbox_inches as a string, perhaps this is why it didn"t work earlier for you.

    Reduce left and right margins in matplotlib plot

    Answer #2

    I cannot claim I know exactly why or how my “solution” works, but this is what I had to do when I wanted to plot the outline of a couple of aerofoil sections — without white margins — to a PDF file. (Note that I used matplotlib inside an IPython notebook, with the -pylab flag.)

    plt.gca().set_axis_off()
    plt.subplots_adjust(top = 1, bottom = 0, right = 1, left = 0, 
                hspace = 0, wspace = 0)
    plt.margins(0,0)
    plt.gca().xaxis.set_major_locator(plt.NullLocator())
    plt.gca().yaxis.set_major_locator(plt.NullLocator())
    plt.savefig("filename.pdf", bbox_inches = "tight",
        pad_inches = 0)
    

    I have tried to deactivate different parts of this, but this always lead to a white margin somewhere. You may even have modify this to keep fat lines near the limits of the figure from being shaved by the lack of margins.
