Returns the number of elements of the specified value Other operations that we can perform on a list are following: Method NameĪdd the elements of the list to the end of the current list #this will add the value at the end of the list. #this will replace the value at the index 6. #this will get the values from index 2 until index 6. We use indexes to access values from a string. To declare a list we use the square brackets. Tuple, set and dictionary are the other collection data type of python.Ī list is ordered and changeable, unlike strings. When we are choosing a collection type, it is important to understand the functionality and limitations of the collection. List is one of the four collection data type that we have in python. Now that we have understood numbers and strings, lets understand the relatively complex data types. #this will return the strings starting at index 1 until the index 4. #this will replace the letter 'e' with 'E' Strings are immutable in nature, which means you cannot change a string once replaced. To access the values in a string, we use the indexes and square brackets. We denote or declare the string values inside single quotes or double quotes. Python does not have a character data type, a single character is also considered as a string. Strings in python are used to represent unicode character values. Imaginary values are denoted with ‘j’ at the end of the number.īoolean is used for categorical output, since the output of boolean is either true o r false. It will return the type of the mentioned variable data type.įloat data type is used to represent decimal point values.Ĭomplex numbers are used to represent imaginary values. To check the type of any variable data type, we can use the type() function. # it will be the integer as long as the value is a whole number. Integers are used to represent whole number values. Following are the sub-types of numerical data type: In numerical data there are 4 sub types as well. Numerical data type holds numerical value. Although there is one more data type range which is often used while working with loops in python. Data Types In PythonĪccording to the properties they possess, there are mainly six python data types. Data types are classes and variables are the instances of these classes. Lets take a look at the python data types.Įvery value that we declare in python has a data type.
