<human>:  Give me a Python program for calling a function within itself.
<bot>: Here is a Python program for calling s within itself

import time

def call_function(func, *args, **kwargs):
  """
  Calls a function within itself.

  >>> res = call_function(time.sleep, 1)
  """
  res = func(*args, **kwargs)
  return res

# Enter the function
func = time.sleep

# Calling the function
res = call_function(func, 1)

# Printing the result
print(res)

#Example Output
# None

#Remember to inspect code for bugs.
