you have to remember to mount your drive again. In the following example you create a file readme.txt in a /content/drive/MyDrive/ul/test/ folder with the content:

and then you read its content back:

• Step 1: mount Google Drive
  
  Python

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

  1 2	from google.colab import drive drive.mount('/content/drive')

  
  
  Mounted at /content/drive

  1	Mounted at /content/drive

• Step 2: save data
  
  Python

  import os pathComponents = ['/content','drive','MyDrive','ul','test'] fileName = 'readme.txt' path = os.path.join(*pathComponents, fileName) print(path) with open(path, 'w') as f: f.write('readme')

  1 2 3 4 5 6 7 8

  import os   pathComponents = ['/content','drive','MyDrive','ul','test'] fileName = 'readme.txt' path = os.path.join(*pathComponents, fileName) print(path) with open(path, 'w') as f:   f.write('readme')

  
  Output:
  
  /content/drive/MyDrive/ul/test/readme.txt

  1	/content/drive/MyDrive/ul/test/readme.txt

• Step 3: load data
  
  Python

  pathComponents = ['/content','drive','MyDrive','ul','test'] fileName = 'readme.txt' path = os.path.join(*pathComponents, fileName) print(path) with open(path, 'r') as f: lines = f.readlines() for line in lines: print(line)

  1 2 3 4 5 6 7 8 9

  pathComponents = ['/content','drive','MyDrive','ul','test'] fileName = 'readme.txt' path = os.path.join(*pathComponents, fileName) print(path) with open(path, 'r') as f:   lines = f.readlines()     for line in lines:     print(line)

  
  Output:
  
  /content/drive/MyDrive/ul/test/readme.txt readme

  1 2	/content/drive/MyDrive/ul/test/readme.txt readme
