The str() function is meant to return representations of values which are fairly human-readable, while repr() is meant to generate representations which can be read by the interpreter (or will force a SyntaxError if there is not equivalent syntax). For objects which don't have a particular ...
If at least one ofencodingorerrorsis given,objectshould be abytes-like object(e.g.bytesorbytearray). In this case, ifobjectis abytes(orbytearray) object, thenstr(bytes,encoding,errors)is equivalent tobytes.decode(encoding,errors). Otherwise, the bytes object underlying the buffer object is ...

"He said his name is 'Fred'." >>> f"He said his name is {repr(name)}." # repr() is equivalent to !r "He said his name is 'Fred'." >>> width = 10 >>> precision = 4 >>> value = decimal.Decimal("12.34567") >>> f"result: {value:{width}.{precision}}" # nested fie...
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 Binary Sequence Types — bytes, bytearray, ...

As a final example of why you should haveUserStringin your Python tool kit, say that you need a mutable string-like class. In other words, you need a string-like class that you can modify in place. Unlikelistsanddictionaries, strings don’t provide the.__setitem__()special method, beca...
Python date.__str__() MethodThe date.__str__() method returns a string representation of the object. For a date object d, str(d) is equivalent to d.isoformat(). str() is an instance method as it uses an instance of the class.Module...
