如何以某种方式更改 python 字典中的所有键？

Question

So I have this dictionary:

sample = {"accessNumber":"0000093410-20-000010", "symbol": "CVX", "cik": "93410"}

I would like to take the keys of the dictionary and append the string "late_" to the beginning of every key.

so the dictionary will become like this:

sample = {"late_accessNumber":"0000093410-20-000010", "late_symbol": "CVX", "late_cik": "93410"}

Thanks!

Answer 1

sample = {"accessNumber":"0000093410-20-000010", "symbol": "CVX", "cik": "93410"}

new_sample = {'late_'+key: value for key,value in sample.items()}
print(new_sample)

Output:

{'late_accessNumber': '0000093410-20-000010', 'late_symbol': 'CVX', 'late_cik': '93410'}
