parameters: (number, base=2, padding=0)
return_statement: return ''.join(reversed(res or '0'))
docstring: Return a string representation of a number in the given base system.
  
      Parameters
      ----------
      number : int
          The value to convert. Positive and negative values are handled.
      base : int, optional
          Convert `number` to the `base` number system. The valid range is 2-36,
          the default value is 2.
      padding : int, optional
          Number of zeros padded on the left. Default is 0 (no padding).
  
      Returns
      -------
      out : str
          String representation of `number` in `base` system.
  
      See Also
      --------
      binary_repr : Faster version of `base_repr` for base 2.
  
      Examples
      --------
      >>> np.base_repr(5)
      '101'
      >>> np.base_repr(6, 5)
