In the Box the Phrase Project you will be investigating Strings and how to manipulate them. Python has 5 other types of built-in data types the can be managed the same way as a String. The skill set you will practice here will allow you to also manipulate: byte sequences, byte arrays, lists, tuples, range objects.
ObjectivesThe student will analyze string manipulation code and create docstrings and comments describing the codes intent. The student explore and use Help>Python Manuals to help them in creating their docstrings and comments. (hint: search the index for string, then look for methods ) The code will include: - single character from a string: [x]
- a sub string: [start:stop]
- negative subscripts(or index): [:-2]
- string concatenation: + and *#
- length of a string: len()
- using a for loop to access one character at time
- replacing one sub string for another sub string: .replace(this, that)
- find the starting location of a sub string: .find(this)
- divide a string in two about the first occurrence of a string: .partition(s)
- place all words in a list: .split()
- sort a list: .sort()
- center a phrase: .center(#)
- chr() and ord()
Program Description
Download the attached python file. Using docstrings and comments, document each function describing the intent of the code. - Completing CS Circles 7A will help you understand this code
- Investigate each function by removing the comment # tag in the main()
- change some of the phrases and numbers being used to see how the code output will change.
- look at the 40 built in string methods available in Python
