String Basics¶

Assume two variables, last_name and first_name, have been defined and refer to strings. Write an assignment statement to make a new string, name, that is the concatenation of first_name and last_name with a space between. # replace this comment with your code ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(name, 'Abraham Lincoln') myTests().main()

Remember that you use + to concatenate strings. Remember that you have to put a space between the first and last names.

name = first_name + ' ' + last_name

Assume two variables, last_name and first_name, have been defined and refer to strings. Write an assignment statement to make a new string, name, that is the concatenation of the first initial of first_name and last_name with a space between. # replace this comment with your code ==== from unittest.gui import TestCaseGui class myTests(TestCaseGui): def testOne(self): self.assertEqual(name, 'A Lincoln') myTests().main()

The first character in a string is accessed by indexing at 0. E.g.,

greeting = ‘hello’

firstLetter = greeting[0]

name = first_name[0] + ' ' + last_name

Write a two-line program to read in a string from the user and then print out the length of that string. # replace this comment with your code ====

Use len(theString) to get the length of the string.

userStr = input("Enter a string: ") print(len(userStr))

Write a small program that asks the user for a string and then prints out the first and last characters of that string. E.g.,

Enter a string: Hello, world

First and last characters are: H d
# replace this comment with your code ====

Use -1 as the index to get the last character of the string.

userInput = input("Enter a string: ") print("First and last characters are:", userInput[0], userInput[-1])
