In [1]: list?
Init signature: list(iterable=(), /)
Docstring:
Built-in mutable sequence.
 
If no argument is given, the constructor creates a new empty list.
The argument must be an iterable if specified.
Type:           type
Subclasses:     _HashedSeq, StackSummary, SList, _ImmutableLineList, FormattedText, NodeList, _ExplodedList, Stack, _Accumulator
 
In [2]: map?
Init signature: map(self, /, *args, **kwargs)
Docstring:
map(func, *iterables) --> map object
 
Make an iterator that computes the function using arguments from
each of the iterables.  Stops when the shortest iterable is exhausted.
Type:           type
Subclasses:
 
In [3]: float?
Init signature: float(x=0, /)
Docstring:      Convert a string or number to a floating point number, if possible.
Type:           type
Subclasses:
 
In [4]: input?
Signature: input(prompt=None, /)
Docstring:
Read a string from standard input.  The trailing newline is stripped.
 
The prompt string, if given, is printed to standard output without a
trailing newline before reading input.
 
If the user hits EOF (*nix: Ctrl-D, Windows: Ctrl-Z+Return), raise EOFError.
On *nix systems, readline is used if available.
Type:      builtin_function_or_method
 
In [5]: str.split?
Signature: str.split(self, /, sep=None, maxsplit=-1)
Docstring:
Return a list of the words in the string, using sep as the delimiter string.
 
sep
  The delimiter according which to split the string.
  None (the default value) means split according to any whitespace,
  and discard empty strings from the result.
maxsplit
  Maximum number of splits to do.
  -1 (the default value) means no limit.
Type:      method_descriptor
