Python 3 has a clear difference between the sequence of characters and the sequence of raw data machine format – bytes. Both types of binary representation of string type of data. Binary sequence typesīytes and bytearray are part of binary sequence types in Python. Those methods are bound to string type of data only. Because strings are objects it use their specific built-in method like upper, lowercase, split, encode and many more. Strings can be indexed and sliced which is one of a great way to manipulate strings. Check later in text details about this feature. Strings are immutable which means that original string objects cannot be modified in any way. Encoding and decoding is done automatically while reading and writing data. It is your choice which type of encoding you will use. Array of bytes? Yes, they are array of bytes with Unicode representation. Strings in Python 3.x are array bytes representing Unicode characters. Strings represent text sequence type and one of the most popular data types to operate. Slicing the sequence takes only part of the sequence. Indexed means that each element can be accessed by its index. Sequence types include all data types that are ordered in position in the way they can be indexed and sliced. Sequence types (Strings, Lists, Tuples, Ranges, Bytes, ByteArray) Octal start with 0o or 0O followed by digits (0-7).
Hexadecimal numbers are represented by hexadecimal digits (A-F, 0-9). Integer numbers can be also represented by hexadecimal (base16), octal (base 8) or binary (base2) format. You can store numbers between –92233720368547758372036854775807.įloats are positive and negative decimal numbers and complex numbers. Integer are positive and negative whole numbers including zero. Numeric data types in Python 3.x are divided into three main types: integer, float and complex. Sequence types (strings, lists, tuples, ranges, bytes, bytearray).
