Shakespeare

How many times does the word 'love' appear in Shakespeare's plays? Is it possible to find negative passages using a list of keywords? We'll use Python to practice our skills and answer questions like these.

Setup

We'll need additional setup here.

Goals

• Have fun using Python to learn basic data science.
• Practice searching for information in text documents
• Practice manipulating strings
• Practice using loops
• Practice using lists
• Practice using dictionaries.
• Get experience with regular expressions.

Skills & Exercises

Strings

• Checking if two strings are equal

>>> s = "mama"
>>> s == "mama"
True
>>> s == "papa"
False

• Checking if a string contains another as a substring

>>> s = "mama"
>>> s in "I love mama"
True
>>> "day" in "Saturday"
True
>>> "Day" in "Saturday"
False
>>> Sat = "Saturday"
>>> "day" in Sat
True

File Operations

• Open a file

>>> M_S=open("A Midsummer-Night's Dream.txt", "r")
>>> M_S
<open file "A Midsummer-Night's Dream.txt", mode 'r' at 0x102d04660>

• Read a line

>>> M_S = open("A Midsummer-Night's Dream.txt", "r")
>>> line = M_S.readline()
>>> print line
< Shakespeare -- A MIDSUMMER-NIGHT'S DREAM >

• Read a file line by line until the end of file (also known as <cod> eof )

>>> for eachline in M_S:
>>> # Do something here with each line read
...
