How to break from the while loop? For Python string type

# Let's create a file and write it to disk.
filename = "test.dat"
# Let's create some data:
done = 0
namelist = []
while not done:
    name = raw_input("Enter a name:")
    if type(name) == type(""):
        namelist.append(name)
    else:
        break

For the Python code above, I tried, but could not break from the while loop. It always asks me to "Enter a name:", whatever I input. How to break from the loop?

This is because raw_input always returns a string, i.e., type(name) == type("") is always true. Try:

while True:
    name = raw_input("Enter a name: ")
    if not name:
        break
    ...

while True:
    name = raw_input("Enter a name:")
    if name:
        namelist.append(name)
    else:
        break

This breaks when entered nothing
