AttributeError: 'str' object has no attribute 'CreateFile'

Question

In my notebook I have a dataset and then the implementation to copy the data from that structure to another dataset. When I do this I get the error message "AttributeError: 'str' object has no attribute 'CreateFile'". From what I understand the problem is in the key field, but I get the same message:

Data columns (total 4 columns):
  # Column Non-Null Count Dtype
--- ------ -------------- -----
  0 reviewId 601786 non-null object
  1 content 600453 non-null object
  2 score 601786 non-null int64
  3 replyContent 47459 non-null object
dtypes: int64(1), object(3)

Implementation in Python

dfOriginal.to_csv('dfCopia.csv', index=False)
file = "myDrive".CreateFile({'title': 'dfCopia.csv', 'parents': [{'id': reviewId}]})
file.Upload()

How can I solve this problem?
