Python: list with tuples to a file

I have few list value which are shown as below and want to print the same to a text file in python.

But I couldn't able to write to a file.

Could anyone please help me how to print the list with tuples to a file .

My code:
======

fout=open('output.txt','w')
mylist =  [('-1', 'limit-minimum 0 maximum 16', '')]
fout.write([tuple(line)])

expected output in output.txt
===================
[('-1', 'limit-minimum 0 maximum 16', '')]

Try converting the tuple to a string first...

string="[" + str(mylist[0]) + "]"
fout.write(string)
