6.2.2. Random User: Generate Random User Data in One Line of Code

Have you ever wanted to create fake user data for testing? Random User Generator is a free API that generates random user data. Below is how to download and use this data in your code.

import json
from urllib.request import urlopen

# Show 2 random users
data = urlopen("https://randomuser.me/api?results=2").read()
users = json.loads(data)["results"]

6.2.3. fetch_openml: Get OpenML’s Dataset in One Line of Code

OpenML has many interesting datasets. The easiest way to get OpenML’s data in Python is to use the sklearn.datasets.fetch_openml method.

In one line of code, you get the OpenML’s dataset to play with!

from sklearn.datasets import fetch_openml

monk = fetch_openml(name="monks-problems-2", as_frame=True)
  attr1 attr2 attr3 attr4 attr5 attr6
0     1     1     1     1     2     2
1     1     1     1     1     4     1
2     1     1     1     2     1     1
3     1     1     1     2     1     2
4     1     1     1     2     2     1
5     1     1     1     2     3     1
6     1     1     1     2     4     1
7     1     1     1     3     2     1
8     1     1     1     3     4     1
9     1     1     2     1     1     1

6.2.4. Autoscraper

!pip install autoscraper

If you want to get the data from some websites, Beautifulsoup makes it easy for you to do so. But can scraping be automated even more? If you are looking for a faster way to scrape some complicated websites such as Stackoverflow, Github in a few lines of codes, try autoscraper.

All you need is to give it some texts so it can recognize the rule, and it will take care of the rest for you!

from autoscraper import AutoScraper

url = "https://stackoverflow.com/questions/2081586/web-scraping-with-python"

wanted_list = ["How to check version of python modules?"]

scraper = AutoScraper()
result = scraper.build(url, wanted_list)

for res in result:
How to execute a program or call a system command?
What are metaclasses in Python?
Does Python have a ternary conditional operator?
Convert bytes to a string
Does Python have a string 'contains' substring method?
How to check version of python modules?

6.2.5. pandas-reader: Extract Data from Various Internet Sources Directly into a Pandas DataFrame

!pip install pandas-datareader

Have you wanted to extract series data from various Internet sources directly into a pandas DataFrame? That is when pandas_reader comes in handy.

Below is the snippet to extract daily data of AD indicator from 2008 to 2018.

import os
from datetime import datetime
import pandas_datareader.data as web

df = web.DataReader(
    start=datetime(2008, 1, 1),
    end=datetime(2018, 2, 28),

6.2.6. pytrends: Get the Trend of a Keyword on Google Search Over Time

!pip install pytrends

If you want to get the trend of a keyword on Google Search over time, try pytrends.

In the code below, I use pytrends to get the interest of the keyword “data science” on Google Search from 2016 to 2021.

from pytrends.request import TrendReq
pytrends = TrendReq(hl="en-US", tz=360)
pytrends.build_payload(kw_list=["data science"])

df = pytrends.interest_over_time()
df["data science"].plot(figsize=(20, 7))

6.2.7. snscrape: Scrape Social Networking Services in Python

If you want to scrape social networking services such as Twitter, Facebook, Reddit, etc, try snscrape.

For example, you can use snsscrape to scrape all tweets from a user or get the latest 100 tweets with the hashtag #python.

# Scrape all tweets from @KhuyenTran16
snscrape twitter-user KhuyenTran16

# Save outputs
snscrape twitter-user KhuyenTran16 >> khuyen_tweets 

# Scrape 100 tweets with hashtag python
snscrape --max-results 100 twitter-hashtag python

6.2.8. Datacommons: Get Statistics about a Location in One Line of Code

!pip install datacommons

If you want to get some interesting statistics about a location in one line of code, try Datacommons. Datacommons is a publicly available data from open sources (census.gov, cdc.gov, data.gov, etc.). Below are some statistics extracted from Datacommons.

import datacommons_pandas
import plotly.express as px 
import pandas as pd Find the Median Income in California Over Time

median_income = datacommons_pandas.build_time_series("geoId/06", "Median_Income_Person")
median_income.index = pd.to_datetime(median_income.index)
    figsize=(20, 10),
    title="Median Income in California Over Time",
<AxesSubplot:title={'center':'Median Income in California Overtime'}>
../_images/get_data_44_1.png Number of People in the U.S Over Time

def process_ts(statistics: str):
    count_person = datacommons_pandas.build_time_series('country/USA', statistics)
    count_person.index = pd.to_datetime(count_person.index)
    count_person.name = statistics
    return count_person 
count_person_male = process_ts('Count_Person_Male')
count_person_female = process_ts('Count_Person_Female')
count_person = pd.concat([count_person_female, count_person_male], axis=1)

    figsize=(20, 10),
    title="Number of People in the U.S Over Time",
<AxesSubplot:title={'center':'Number of People in the U.S Overtime'}>
../_images/get_data_48_1.png Number of Robberies in the US Over Time

count_robbery = datacommons_pandas.build_time_series(
    "country/USA", "Count_CriminalActivities_Robbery"
count_robbery.index = pd.to_datetime(count_robbery.index)
    figsize=(20, 10),
    title="Number of Robberies in the US Over Time",
<AxesSubplot:title={'center':'Number of Robberies in the US Overtime'}>
