Python Data Analytics

Pandas is a numerical package used extensively in data science. You can call the install the pandas package by

pip install pandas

Like numpy, the underlying routines are written in C with improved performance


In [1]:
import pandas
pandas.__version__


Out[1]:
'0.23.4'

In [2]:
import pandas as pd
import numpy as np

Built-In Documentation in jupyter

For example, to display all the contents of the pandas namespace, you can type

ipython
In [3]: pd.<TAB>

And to display Pandas's built-in documentation, you can use this:

ipython
In [4]: pd?

The Pandas Series Object

A Pandas Series is a one-dimensional array of indexed data.


In [3]:
data = pd.Series([1., 2., 3., 4.])
data


Out[3]:
0    1.0
1    2.0
2    3.0
3    4.0
dtype: float64

In [4]:
data = pd.Series([1, 2, 3, 4])
data


Out[4]:
0    1
1    2
2    3
3    4
dtype: int64

To retrieve back the underlying numpy array, we have the values attribute


In [5]:
data.values


Out[5]:
array([1, 2, 3, 4])

The index is an array-like object of type pd.Index.


In [6]:
data.index


Out[6]:
RangeIndex(start=0, stop=4, step=1)

Slicing and indexing just like Python standard list


In [7]:
data[1]


Out[7]:
2

In [8]:
data[1:3]


Out[8]:
1    2
2    3
dtype: int64

The Pandas Index

The index is useful to denote each record, the datatypes of the index can be varied. You can think of another numpy array binded to the data array.


In [9]:
data = pd.Series([1, 2, 3, 4],
                 index=['a', 'b', 'c', 'd'])
data


Out[9]:
a    1
b    2
c    3
d    4
dtype: int64

If we supply a dictionary to the series, it will be constructed with an index. By default, a Series will be created where the index is drawn from the sorted keys.


In [10]:
location = {
            'Berlin': (52.5170365, 13.3888599),
            'London': (51.5073219, -0.1276474),
            'Sydney': (-33.8548157, 151.2164539),
            'Tokyo': (34.2255804, 139.294774527387),
            'Paris': (48.8566101, 2.3514992),
            'Moscow': (46.7323875, -117.0001651)
           }
location = pd.Series(location)
location


Out[10]:
Berlin          (52.5170365, 13.3888599)
London          (51.5073219, -0.1276474)
Sydney        (-33.8548157, 151.2164539)
Tokyo     (34.2255804, 139.294774527387)
Paris            (48.8566101, 2.3514992)
Moscow        (46.7323875, -117.0001651)
dtype: object

In [11]:
location['Berlin']


Out[11]:
(52.5170365, 13.3888599)

Unlike a dictionary, though, the Series also supports array-style operations such as slicing


In [12]:
location['London':'Paris']


Out[12]:
London          (51.5073219, -0.1276474)
Sydney        (-33.8548157, 151.2164539)
Tokyo     (34.2255804, 139.294774527387)
Paris            (48.8566101, 2.3514992)
dtype: object

The Pandas DataFrame Object

The pandas dataframe object is a very powerful table like object.


In [13]:
location = {
            'Berlin': (52.5170365, 13.3888599),

Read Data

pandas has built-in data readers, you can type pd.read<TAB> to see what data format does it support: we will focus in csv file which is widely used

We have some data downloaded from airbnb, you can find it in the folder, you may also download the file by executing the following code:


In [18]:
import urllib.request
urllib.request.urlretrieve(
    'http://data.insideairbnb.com/taiwan/northern-taiwan/taipei/2018-11-27/visualisations/listings.csv',

Missing Data in Pandas

Missing data is very important in pandas dataframe/series operations. Pandas do element-to-element operations based on index. If the index does not match, it will produce a not-a-number (NaN) results.


In [24]:
A = pd.Series([2, 4, 6], index=[0, 1, 2])
B = pd.Series([1, 3, 5], index=[1, 2, 3])
A + B


Out[24]:
0    NaN
1    5.0
2    9.0
3    NaN
dtype: float64

In [25]:
A.add(B, fill_value=0)


Out[25]:
0    2.0
1    5.0
2    9.0
3    5.0
dtype: float64

The following table lists the upcasting conventions in Pandas when NA values are introduced:

Typeclass Conversion When Storing NAs NA Sentinel Value
floating No change np.nan
object No change None or np.nan
integer Cast to float64 np.nan
boolean Cast to object None or np.nan

Pandas treats None and NaN as essentially interchangeable for indicating missing or null values. They are convention functions to replace and find these values:

  • isnull(): Generate a boolean mask indicating missing values
  • notnull(): Opposite of isnull()
  • dropna(): Return a filtered version of the data
  • fillna(): Return a copy of the data with missing values filled or imputed

In [26]:
# Fill Zero
(A + B).fillna(0)


Out[26]:
0    0.0
1    5.0
2    9.0
3    0.0
dtype: float64

In [27]:
# forward-fill
(A + B).fillna(method='ffill')


Out[27]:
0    NaN
1    5.0
2    9.0
3    9.0
dtype: float64

In [28]:
# back-fill
(A + B).fillna(method='bfill')


Out[28]:
0    5.0
1    5.0
2    9.0
3    NaN
