Pylint does not properly process a ctypes variable's value field.

[sidneycadot]

Bug description

"""Demonstrate pylint issue."""

import ctypes

x = ctypes.c_float(1.0)

# The line below produces a strange PyLint warning:
#
#   E1101: Class 'value' has no 'is_integer' member (no-member)
#
# At runtime at least, x.value yields a 'float' value.
# It seems pylint gets tripped up by some ctypes construct.

print(x.value.is_integer())

Configuration

Command used

pylint x.py

Pylint output

x.py:14:6: E1101: Class 'value' has no 'is_integer' member (no-member)
