Python, as a dynamically typed language, allows flexibility in data types. However, when dealing with complex data, there might be times where you need to explicitly convert data types. Understanding this proces
A Pythondictionaryis a group of key-value pairs. The elements in a dictionary are indexed by keys. Keys in a dictionary are required to be unique. Because of the importance of the dictionary data type, a whole chapter covers the dictionary in this Python tutorial. dictionary_simple.py #!/...
Python has the inbuilt functions ofint()andstr()that are used to convert data types. Theint()will convert anything placed within its parameters to an integer values. Likewise, thestr()function converts any value within it’s parameters into a string. There are some restrictions to this howev...
In this tutorial, we will go over the important data types native to Python. This is not an exhaustive investigation of data types, but will help you become familiar with what options you have available to you in Python. Prerequisites You should have Python 3 installed and a programming envir...

string1 ="PYTHON TUTORIAL" See the following statements to access single character from various positions. Strings are immutable Strings are immutable character sets. Once a string is generated, you can not change any character within the string. See the following statements. ...
I’m going to end this tutorial with a few words about slots. Slots can be used to make classes faster and use less memory. Data classes have no explicit syntax for working with slots, but the normal way of creating slots works for data classes as well. (They really are just regular ...

Note: In Python, the built-in functions associated with data types, such as int(), float(), str(), and bytes(), are classes with a function-style name. The Python documentation calls them functions, so you’ll follow that practice in this tutorial. However, keep in mind that something...
