Question

How can i write keys of a dictionary to a text file line by line, i.e. one key per line? If there is any link pointing to the same, please direct me to that link. I can find loading text file contents into a dictionary, but i am not able to find the vice-versa.

If all you want to print is the keys (i.e. not the values) you can simply iterate over the dict:

with open("filename", "w") as f:
    for key in dict:
        print >>f, key

or in Python 3, with the new print function:

with open("filename", "w") as f:
    for key in dict:
        print(key, file=f)
