Using the Bitcoin python library to generate Private Key [Noob question]

I have done pip install bitcoin and then wrote the below code:

from bitcoin import *
private_key = random_key()
print(private_key)

Now I am getting this error:

Traceback (most recent call last):
  File "/Users/praveen/Documents/code/sandbox/python/bitcoinkey.py", line 1, in <module>
    from bitcoinkey import *
  File "/Users/praveen/Documents/code/sandbox/python/bitcoinkey.py", line 2, in <module>
    private_key = random_key()
NameError: name 'random_key' is not defined

Any idea why 'random_key' is not defined?

Thanks, Just getting started with tinkering.

Try this:

import bitcoin, base58, ecdsa, requests, smtplib, multiprocessing, blockchain
import gc
import sys
gc.collect()

while True:

    private_key = random_key()
    public_key = privtopub(private_key)
    address = pubtoaddr(public_key)

    with open("btc.txt", "r") as m:
        add = m.read().split()
        for ad in add:
                continue
        if address in add:
            print("Found"+ " " +address+ ' ' +private_key)
            data = open("data.txt","a")
            data.write(print(address+ ' ' +private_key+ ' ' +"\n")) 
            data.close()

        else:
            print(address+ ' ' +private_key)
del (address)
del (private_key)
os.execv(sys.executable, ['python'] + [sys.argv[0]])
