Section 10.25 Strings and Lists
Two of the most useful methods on strings involve lists of strings. The
split method breaks a string into a list of words. By default, any number of whitespace characters is considered a word boundary.
An optional argument called a delimiter can be used to specify which characters to use as word boundaries. The following example uses the string
ai as the delimiter:
Notice that the delimiter doesn’t appear in the result.
The inverse of the
split method is
join. You choose a desired separator string, (often called the glue) and join the list with the glue between each of the elements.
The list that you glue together (
wds in this example) is not modified. Also, you can use empty glue or multi-character strings as glue.
Check your understanding
What is printed by the following statements?
myname = "Edgar Allan Poe"
namelist = myname.split()
init = ""
for aname in namelist:
init = init + aname
Three characters but not the right ones. namelist is the list of names.
Too many characters in this case. There should be a single letter from each name.
Yes, split creates a list of the three names. The for loop iterates through the names and creates a string from the first characters.
That does not make any sense.
