Exercise 6.5 Take the following Python code that stores a string:‘
str = 'X-DSPAM-Confidence:0.8475'
Use find and string slicing to extract the portion of the string after the colon character and then use the float function to convert the extracted string into a floating point number.
Exercise 6.6 Read the documentation of the string methods at docs.python.org.lib/string-methods.html.You might want to experiment with some of them to make sure you understand how they work. strip and replace are particularly useful.
The documentation uses a syntax that might be confusing. For example, in find(sub[, start[, end]]), the brackets indicate optional arguments. So sub is required, but start is optional, and if you include start, then end is optional.
