Python Notes

Strings

Single or Double quotes are fine for declaring strings. Also for multiline strings triple-double quotes can be used """ string """ this has the benifit that you don't have to escape the single or double quotes.

getting string length

mystring = " this is a text string." 
len(mystring)

String operations

>>> mystring = "Hello world"
>>> mystring.
mystring.capitalize(    mystring.find(          mystring.isdecimal(     mystring.istitle(       mystring.partition(     mystring.rstrip(        mystring.translate(
mystring.casefold(      mystring.format(        mystring.isdigit(       mystring.isupper(       mystring.replace(       mystring.split(         mystring.upper(
mystring.center(        mystring.format_map(    mystring.isidentifier(  mystring.join(          mystring.rfind(         mystring.splitlines(    mystring.zfill(
mystring.count(         mystring.index(         mystring.islower(       mystring.ljust(         mystring.rindex(        mystring.startswith(
mystring.encode(        mystring.isalnum(       mystring.isnumeric(     mystring.lower(         mystring.rjust(         mystring.strip(
mystring.endswith(      mystring.isalpha(       mystring.isprintable(   mystring.lstrip(        mystring.rpartition(    mystring.swapcase(
