Charles Kelly explains how to use vectorized operations for element-by-element calculations within Pandas series.
- [Narrator] The Vectorized Operations file…from your exercise's files folder…is pre-populated with import statements…for pandas, numpy and a series created…from a Python dictionary.…Place your cursor in this cell,…then execute this cell by pressing shift + enter.…In the following cell, we create a dictionary…with the keys, a, b and c…and the values 45, minus 19.5…and 4,444.…Then we take the dictionary and we pass it as an argument…to the series function.…
Then we display my_series.…We can add the elements in this series,…those elements that came from the dictionary,…without writing a loop.…We copy my_series and paste it, plus itself,…as we execute the cell, we see that each element…is exactly twice the value of the elements…in the original series.…Also note that the value…of the original series doesn't change.…We can note this by creating a new cell, esc + b…and typing the name my_series.…
Press shift + enter to display it.…So, we added the series together without writing a loop.…We didn't change the value of the series itself.…
