I am doing something like this :
import numpy as np
import timeit
a = np.arange(1000)
%timeit a**2
Error :
TypeError: 'module' object is not callable
I want to print the time for the execution of statement a**2 in pycharm , can anyone please help me
Note : %timeit a**2 in working fine in Jupyter Notebook

The syntax to execute your function inside timeit() on the command line is as follows: python -m timeit [-n N] [-r N] [-s S] [-t] [-c] [-h] [code statement ...] Command line parameters: -n N: the number of times you want the code to execute.
The Python timeit() method accepts the code as a string and returns the execution time in seconds. On the contrary, the default_timer() method returns the time of its execution. The repeat() method calls the timeit() method a number of specified times.
%%time is a magic command. It's a part of IPython. %%time prints the wall time for the entire cell whereas %time gives you the time for first line only. Using %%time or %time prints 2 values: CPU Times.
Source code: Lib/timeit.py. This module provides a simple way to time small bits of Python code. It has both a Command-Line Interface as well as a callable one. It avoids a number of common traps for measuring execution times.
%timeit and %%timeit are Jupyter magic commands, and only work inside IPython/Jupyter. They will not work in PyCharm or in Python scripts in general.
If you have PyCharm Professional, you can profile your script by clicking the profile button (to the right of the 'run', 'debug', and 'run with coverage' buttons).
If you don't you can time any Python 3 script by inserting
from datetime import datetime
start = datetime.now()
and
print(datetime.now() - start)
at the end.
