Question

Python has built-in methods to support different manipulations of string data types. Answer what the following code will print following each Python method.

Str = "Tennessee State University"

      print(len(str))
      print(str.lower())
      print(str.upper())

      substr = “State”

      print (str.index(substr))
      print (str.startswith(“State”))
      print (str.split())
      print (str.find(substr))
      print (str.partition(“State”))

myList = str.split()
for words in myList:
       print (words)

newStr = “TN, TX, NY, MA, VA, PA, LA, CA”
myStates = newStr.split(‘,’)
print (myStates)

Show with examples if the above string operations are supported by C++ library OR the Java String class.

Answer 1

str = "Tennessee State University"

print(len(str)) ###prints length of string ie.26
print(str.lower())##prints all letters in lower case ie: tennessee state university
print(str.upper())#prints TENNESSEE STATE UNIVERSITY
substr ="State"
print (str.index(substr))# prints 10
print (str.startswith("State")) #prints false
print (str.split())# prints ['Tennessee', 'State', 'University']
print (str.find(substr)) #prints 10
print (str.partition("State")) # prints ('Tennessee ', 'State', ' University')
myList = str.split()
for words in myList:
print (words) #prints Tennessee State University
newStr = "TN, TX, NY, MA, VA, PA, LA, CA"
myStates = newStr.split(',')
print (myStates) #prints ['TN', ' TX', ' NY', ' MA', ' VA', ' PA', ' LA', ' CA']
