Sometimes, we want to get the day of week given a date with Python.

In this article, we’ll look at how to get the day of week given a date with Python.

How to get the day of week given a date with Python?

To get the day of week given a date with Python, we can use the weekday method.

For instance, we write

import datetime

d = datetime.datetime.today().weekday()

to get today’s datetime with datetime.datetime.today().

And then we call weekday on the datetime to get the day of the week of today as the number.

d should be between 0 and 6 where 0 is Monday and 6 is Sunday.

Conclusion

To get the day of week given a date with Python, we can use the weekday method.

Sometimes, we want to get the path and name of the file that is currently executing with Python.

In this article, we’ll look at how to get the path and name of the file that is currently executing with Python.

How to get the path and name of the file that is currently executing with Python?

To get the path and name of the file that is currently executing with Python, we can use the os.path.realpath method.

For instance, we write

import os

os.path.realpath(__file__)

to call os.path.realpath with __file__ to get the full path of the current script.

We get the actual path rather than the path of the symlink.

__file__ has the relative path of the current script.

Conclusion

To get the path and name of the file that is currently executing with Python, we can use the os.path.realpath method.

Sometimes, we want to get a function name as a string with Python.

In this article, we’ll look at how to get a function name as a string with Python.

How to get a function name as a string with Python?

To get a function name as a string with Python, we can use the __name__ property.

For instance, we write

my_function.__name__

to get the __name__property of my_function to return my_function‘s name as a string.

Conclusion

To get a function name as a string with Python, we can use the __name__ property.

Sometimes, we want to prompt for user input and read command-line arguments with Python.

In this article, we’ll look at how to prompt for user input and read command-line arguments with Python.

How to prompt for user input and read command-line arguments with Python?

To prompt for user input and read command-line arguments with Python, we can use the input function.

For instance, we write

text = input("prompt")

to call input with the prompt text.

And we get the user input value from the return value of input.

Conclusion

To prompt for user input and read command-line arguments with Python, we can use the input function.

Sometimes, we want to convert UTC datetime string to local datetime with Python.

In this article, we’ll look at how to convert UTC datetime string to local datetime with Python.

How to convert UTC datetime string to local datetime with Python?

To convert UTC datetime string to local datetime with Python, we can call the fromtimestamp and utcfromtimestamp methods.

For instance, we write

from datetime import datetime
import time

def datetime_from_utc_to_local(utc_datetime):
    now_timestamp = time.time()
    offset = datetime.fromtimestamp(now_timestamp) - datetime.utcfromtimestamp(now_timestamp)
    return utc_datetime + offset

to create the datetime_from_utc_to_local function that takes the utc_datetime value.

In it, we get the local time offset from UTC with

offset = datetime.fromtimestamp(now_timestamp) - datetime.utcfromtimestamp(now_timestamp)

Then we add the offset to the utc_datetime and return the sum to get the local time.

Conclusion

To convert UTC datetime string to local datetime with Python, we can call the fromtimestamp and utcfromtimestamp methods.
