Python in Google Colaboratory - How to create, write and read files in google drive

Question

I tried using the code below to create a file but it didn't work when I tried to search it in my drive. Here is the link to my code if you need to see the full thing. https://colab.research.google.com/drive/1N436bntHOf146ZMGVBeSh5EXBuYAjvQY?usp=sharing

Here is the code I used to create and write a file.

output = open("sequences.fasta", "w")
output.writelines('>' + firstheader + '\n' + seq1 + '\n')
output.writelines('>' + secondheader + '\n' + seq2.upper() + '\n')
output.writelines('>' + thirdheader + '\n' + seq3.replace('-', '') + '\n') 

Answer 1

Setup

You'll need to mount your google drive:

from google.colab import drive
drive.mount('/gdrive')

I would advise you to go to the default repository for the notebooks:

!cd '/gdrive/My Drive/Colab Notebooks/'

Actual Solution

When you are done you have to flush and unmount to see the changes in Gdrive

drive.flush_and_unmount()

Just a download

Or you can use directly files to download it:

from google.colab import files
files.download('sequences.fasta')
