Then print type2
Create a variable called type3 and set it to the type of an string
Then print type3

# Here's an example for you:
type0 = type(True)
print type0

# Exercise 0 : Generic Imports
"""
Type import math
Print the square root of 25
For example, print math.sqrt(36) will print 6.0
"""
from math import*
print sqrt(144)
# Exercise 1 : Function Imports
"""
Change the import so that you only import the sqrt function, like this:
from math import sqrt
Print the square root of 100
For example, print sqrt(81) will print 9.0
"""
# Exercise 2 : Function Imports
"""
Change the import so that you import everything from the math module, like this:
from math import *
Print the square root of 144
For example, print sqrt(25) will print 5.0
