Sometimes, we want to print a date in a regular format with Python.

In this article, we’ll look at how to print a date in a regular format with Python.

How to print a date in a regular format with Python?

To print a date in a regular format with Python, we can use the strftime method.

For instance, we write

import datetime

print(datetime.datetime.now().strftime("%Y-%m-%d %H:%M"))

to call strtftime method of the datetime that has the current datetime as its value.

We call it with a string to specify how it’s formatted.

%Y adds the 4 digit year.

%m adds the 2 digit month.

%d adds the 2 digit day of the month.

%H adds the 2 digit hour.

And %M adds the 2 digit minutes.

Conclusion

To print a date in a regular format with Python, we can use the strftime method.

Sometimes, we want to convert hex string to int in Python.

In this article, we’ll look at how to convert hex string to int in Python.

How to convert hex string to int in Python?

To convert hex string to int in Python, we can use the int function with the radix argument.

For instance, we write

x = int("deadbeef", 16)

to call int to convert the 'deadbeef' hex string to a decimal int by calling int with 'deadbeef' and 16.

Conclusion

To convert hex string to int in Python, we can use the int function with the radix argument.

Sometimes, we want to draw images using Python pygame.

In this article, we’ll look at how to draw images using Python pygame.

How to draw images using Python pygame?

To draw images using Python pygame, we can use the blit method.

For instance, we write

my_image = pygame.image.load("image.bmp")
image_rect = myimage.get_rect()

while true:
    #...

    screen.fill(black)
    screen.blit(my_image , image_rect)
    pygame.display.flip()

to load the image.bmp image with

myimage = pygame.image.load("myimage.bmp")

The in an infinite while loop, we call screen.blit with the my_image image and the image_rect to draw the image.

Conclusion

To draw images using Python pygame, we can use the blit method.

Sometimes, we want to schedule updates in Python tkinter.

In this article, we’ll look at how to schedule updates in Python tkinter.

How to schedule updates in Python tkinter?

To schedule updates in Python tkinter, we can use the root.after method.

For instance, we write

import tkinter as tk
import time

class App():
    def __init__(self):
        self.root = tk.Tk()
        self.label = tk.Label(text="")
        self.label.pack()
        self.update_clock()
        self.root.mainloop()

    def update_clock(self):
        now = time.strftime("%H:%M:%S")
        self.label.configure(text=now)
        self.root.after(1000, self.update_clock)

app=App()

to add the update_clock method that calls root.after with the timeout in miiliseconds and the update_clock to update the clock after 1 second.

Conclusion

To schedule updates in Python tkinter, we can use the root.after method.

Sometimes, we want to determine the current script directory with Python.

In this article, we’ll look at how to determine the current script directory with Python.

How to determine the current script directory with Python?

To determine the current script directory with Python, we can use the os.path.dirname method.

For instance, we write

os.path.dirname(os.path.abspath(__file__))

to get the current script’s path with __file__.

Then we get the absolute path of the script with os.path.abspath.

And then we get the folder name from the absolute path with os.path.dirname.

Conclusion

To determine the current script directory with Python, we can use the os.path.dirname method.
