How to remove dot from dictionary key in python

Question

I have python dictionary as follows:

 data=df.to_dict('records')
 print(data)

Gives Output:

    [{'id':'1','quantity.':2,'price':'350'},{'id':'2','quantity.':1,'price':'125'}, 
    {'id':'3','quantity.':4,'price':'500'}]

But while inserting in mongoDB using command collection.insert_many(data) it gives error as follows:

bson.errors.InvalidDocument: key 'quantity.' must not contain '.'

As we cannot store data with special characters in MongoDB, So how can I remove this dot '.' from all keys, So that i can insert data in MongoDB

Answer 1

This comprehension ought to do it.

data = [{k.replace('.', ''): v for k, v in d.items()} for d in data]

Answer 2

If you are using pandas, try:

data=data.rename({'quantity.':'quantity'}, axis='columns')
print(data)

Answer 3

In case of you using pandas, you can rename the specific column:

data = data.rename({'quantity.':'quantity'})

Or you can reassign the whole columns name with new one:

data.columns = ['id', 'quantity', 'price']
