As you can see from the result, the index values start at 0 as expected, but you do not need to use the index to access the item from the list. In summary, you should not write Python code like this: Python for i in range(len(lst_1)): print(lst_1[i]) In this code, ...

Alternatively, you can also choose to plot a numeric variable that exists outside of a DataFrame. This could be data in a Python list or a Numpy array. If you do this, then you can skip the quotation marks around the name. (For the most part, the quotation marks are only required wh...
Alternatively, if you don’t use thedata_frameparameter, you can specify a Python list, a 1D Numpy array, or a list-like object.. If you specify a DataFrame column as the argument to this parameter, the column name should be inside of quotation marks (i.e., you pass the name of th...
the techniques covered here will be the same. If you want to learn more about the requests library, here’s a link - https://realpython.com/python-requests/. Then we have the Pandas library because we're going to save our data into a Pandas DataFrame and then th...

Because pandas stores strings as an array of objects, it has to fall back on slow Python arrays. In contrast to numpy, a Python list has a pointer to a memory-contiguous buffer of pointers, which point to objects stored in memory, but which also reference data stored in other locations....
