# Define a variable containing an integer first
number = 7
# Next, we would have to convert it to a string. But, since the str() method 
# would make our variable's integer a string for a temporary period, 
# we would have to REdefine the entire variable as a string:
number = str(number)
# To prove my method, I will use the type() function to show you that 
# the variable had change permanently:
print(type(number))
