Python Programming in Context, 4th Edition

3.8 Summary

In this chapter, we explored an important Python data type called strings—sequences of characters that provide a wide range of built-in functions, string operators, and methods.

• String operators:

  • Concatenation (+)

  • Repetition (*)

  • Indexing ( [] )

  • Slicing ([:] )

  • Membership (in and not in)

• Length (len) built-in function

• String search methods:

  • find/rfind

  • index/rindex

• String formatting methods:

  • upper

  • lower

  • center

  • ljust

  • rjust

• Other string methods

  • replace

  • count

  • startswith

  • countains

We also introduced Python built-in character functions:

• ord

• chr

We distinguished between positional and keyword parameters with an example using the print function.

We used decomposition to build up a collection of small functions that could be used ...
