numpy.who() function print the NumPy arrays in the given dictionary.

Syntax : numpy.who(vardict = None)
Parameters :
vardict : [dict, optional] A dictionary possibly containing ndarrays.
Return : Returns ‘None’. If there is no dictionary passed in or vardict is None then returns NumPy arrays in the globals() dictionary.

Code #1 :

# Python program explaining 
# numpy.who() function 
           
# importing numpy as geek  
import numpy as geek  
  
a = geek.arange(5) 
b = geek.ones(10) 
  
gfg = geek.who() 
     
print (gfg) 

Output :

a               5                40               int64
b               10               80               float64

Upper bound on total bytes  =       120
None

Code #2 :

# Python program explaining 
# numpy.who() function 
           
# importing numpy as geek  
import numpy as geek  
  
a = geek.arange(3.0) 
b = geek.arange(5.0) 
  
gfg = geek.who() 
     
print (gfg) 

Output :
