Write a method in python to display the elements of list thrice if it is a number and display the element terminated with '#' if it is not a number.
For example, if the content of the list is as follows:
ThisList=['41','DROND','GIRIRAJ','13','ZARA']
414141
DROND#
GIRlRAJ#
131313
ZARA#
def fun(L):
for I in L:
if I.isnumeric():
print(3*I) # equivalently:
print(I+I+I)
else:
print(I+'#')
