Changing Strings with Methods - Python

We can use various methods to change the data in a string. We touched on slicing and concatenation earlier in the article, and I am going to talk about it just a little more here. Before, we replaced an entire word; this time we will only replace part of a word:

speech='A toast, to bread, whom without there would be no taste'

what='No wait that is not right'

print speech

print what

speech=speech[0:51] + 'oa' + speech[52:54]

print speech

Which would produce the following output:

  A toast, to bread, whom without there would be no taste

  No wait that is not right

  A toast, to bread, whom without there would be no toast

We could also use the replace method, which might prove to be a little easier:

speech='A toast, to bread, whom without there would be no taste'

what='No wait that is not right'

print speech

print what

speech=speech.replace('taste','toast')

print speech

Resulting in:

  A toast, to bread, whom without there would be no taste

  No wait that is not right

  A toast, to bread, whom without there would be no toast

This would also be handy if, say, a certain writer by the name of James Payne began dating your mother:

oldFather='Your father is named...whatshisname...'

print oldFather

oldFather=oldFather.replace('whatshisname', 'James Payne the new Hawtness')

print oldFather

And the shocking results:

  Your father is named...whatshisname...

  Your father is named...James Payne the new Hawtness...
