Strings are immutable sequences of Unicode code points. String literals are written in a variety of ways\n\nSingle quotes: 'allows embedded \"double\" quotes' Double quotes: \"allows embedded 'single' quotes\" Triple quoted: '''Three single quotes''', \"\"\"Three double quotes\"\"\"\n\nTriple quoted strings may span multiple lines - all associated whitespace will be included in the string literal.\n\nString literals that are part of a single expression and have only whitespace between them will be implicitly converted to a single string literal. That is, (\"spam \" \"eggs\") == \"spam eggs\".\n\nSee strings for more about the various forms of string literal, including supported escape sequences , and the r (\"raw\") prefix that disables most escape sequence processing.\n\nStrings may also be created from other objects using the str constructor.\n\nSince there is no separate \"character\" type, indexing a string produces strings of length 1. That is, for a non-empty string s, s[0] == s[0:1].\n\npair: object; io.StringIO\n\nThere is also no mutable string type, but str.join or io.StringIO can be used to efficiently construct strings from multiple fragments.\n\nFor backwards compatibility with the Python 2 series, the u prefix is once again permitted on string literals. It has no effect on the meaning of string literals and cannot be combined with the r prefix.\n\nsingle: string; str (built-in class)\n\nReturn a string version of object. If object is not provided, returns the empty string. Otherwise, the behavior of str() depends on whether encoding or errors is given, as follows.\n\nIf neither encoding nor errors is given, str(object) returns type(object).str(object) , which is the \"informal\" or nicely printable string representation of object. For string objects, this is the string itself. If object does not have a ~object.str method, then str falls back to returning repr(object) .\n\nIf at least one of encoding or errors is given, object should be a bytes-like object (e.g. bytes or bytearray). In this case, if object is a bytes (or bytearray) object, then str(bytes, encoding, errors) is equivalent to bytes.decode(encoding, errors) . Otherwise, the bytes object underlying the buffer object is obtained before calling bytes.decode. See binaryseq and bufferobjects for information on buffer objects. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
