Sometimes, we want to convert bytes to a string with Python.

In this article, we’ll look at how to convert bytes to a string with Python.

How to convert bytes to a string with Python?

To convert bytes to a string with Python, we can use the decode method.

For instance, we write:

decoded = b"abcde".decode("utf-8")
print(decoded)

We call decode on a binary string with 'utf-8' to decode it into a regular UTF-8 string.

Therefore, decoded is 'abcde'.

Conclusion

To convert bytes to a string with Python, we can use the decode method.

Sometimes, we want to copy a file in Python.

In this article, we’ll look at how to copy a file in Python.

How to copy a file in Python?

To copy a file in Python, we can use the copyfile function from the shutil module.

For instance, we write:

from shutil import copyfile

src = './foo.txt'
dst = './bar.txt'
copyfile(src, dst)

We call copyfile with the path of the source and destination files respectively.

Now we should see the src file copied to the dst destination if the file specified by the src path exists.

Conclusion

To copy a file in Python, we can use the copyfile function from the shutil module.

Sometimes, we want to concatenate two lists in Python.

In this article, we’ll look at how to concatenate two lists in Python.

How to concatenate two lists in Python?

To concatenate two lists in Python, we can use the + operator.

For instance, we write:

listone = [1, 2, 3]
listtwo = [4, 5, 6]

joinedlist = listone + listtwo
print(joinedlist)

Then joinedlist is [1, 2, 3, 4, 5, 6].

Conclusion

To concatenate two lists in Python, we can use the + operator.

Sometimes, we want to convert a string into datetime with Python.

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

How to convert a string into datetime with Python?

To convert a string into datetime with Python, we can use the datetime.strptime method.

For instance, we write:

from datetime import datetime

datetime_object = datetime.strptime('Jun 1 2025  1:33PM', '%b %d %Y %I:%M%p')
print(datetime_object)

We pass in a date string and a string with the date format of the date in the first argument in it.

%b is the format code for the abbreviated month.

%d is the format code for the day of the month.

%y is the format code for the 4 digit year.

It returns a date object with with the date given in the string in the first argument.

Conclusion

To convert a string into datetime with Python, we can use the datetime.strptime method.

Sometimes, we want to get the last element of a Python list.

In this article, we’ll look at how to get the last element of a Python list.

How to get the last element of a Python list?

To get the last element of a Python list, we can use -1 as the index in the square brackets.

For instance, we write:

some_list = [1, 2, 3]
print(some_list[-1])

Then we see 3 logged since index -1 is the last element of the list.

Conclusion

To get the last element of a Python list, we can use -1 as the index in the square brackets.
