You can substitute this with any other function, including custom ones. For instancec, let's create a function that capitalizes each element in the 'off chance' an element isn't capitalized as it should be:. This results in:. Finally, for a more clean and easy way to pass elements through a function - we can use map. Generally, the map function is used to map values of one collection to another, typically using a different or even reduced format.
For instance, you could map each character to another list of booleans, where each boolean represents if the character is uppercase or not. If you specify the wrong encoding, the best case is your program crashing because it can't decode the data.
For example, if we tried using the str function with UTF , we'd be greeted with:. This is even more important given that Python 3 likes to assume Unicode - so if you are working with files or data sources that use an obscure encoding, make sure to pay extra attention. In Python 2, a bundle of bytes and a string are practically the same thing - strings are objects consisting of 1-byte long characters, meaning that each character can store values. That's why they are sometimes called bytestrings.
This is great when working with byte data - we just load it into a variable and we are ready to print:.

Here, we'll have to use Python 2's Unicode type, which is assumed and automatically used in Python 3.

In Python, there is a DateTime library [1] that has a function or method named strptime that can be used to convert a string in a date-time format. There is another function named strftime that can be used to format the string to a proper DateTime value.
Let us see in the below code example the usage of strptime function that you can use from the DateTime library of Python for conversion of the string to date. In the above example, the string is converted to a proper DateTime Format that is stored in a DateTime object, and then we are printing the Object to get the Output. The code converted the string to a complete DateTime format.
What if you want to convert the same above-mentioned string only as of the date in the yyyy-mm-dd format.
