The complete code is as follows:
from array import *
myArr = array('f',[3, 5, 7,3, 10])
location = myArr.index(7)
print(str("7")+" is at position "+str(location+1))
Explanation:
I made corrections to the third line of the code and I added a line
This line gets the index of 7 from the array myArr using the index keyword
location = myArr.index(7)
This line prints the position of the 7 in the array
print(str("7")+" is at position "+str(location+1))
