Question

Are my answers to Ps0 correct?

Answer 1

Python 2.7 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> lastname = raw_input ("What is your last name? ")
What is your last name? Doe
>>> firstname = raw_input ("What is your first name? ")
What is your first name? Noby
>>> print ("Your name is ", firstname + lastname)
('Your name is ', 'NobyDoe')
>>>

Answer 2

I was just wondering if my answers were correct or should I have done them in a "command line" style where the user is asked along the way for there input?

Answer 3

Right - this is how I coded it when for the command line.

print "Enter your last name:"
answer1 = raw_input("** " )

print "Enter your first name:"
answer2 = raw_input("** ")

print answer2, answer1

Answer 18

Hi to every one. What is recommended book to learn python along with the course?

Answer 19

how do you print in the next line?

Answer 20

Hm. What do you mean by the next line?

Answer 21

HI Ja!

Answer 22

I'd also like to contribute in this topic if you folks don't mind.

I wanted to emulate something similar to the example on the pdf file. I wanted to get these results:

Enter your last name: Doe
Enter your first name: Jane
Your name is: Jane Doe

I wrote down the following for it:

lastname = raw_input('Enter your last name: '); firstname = raw_input('Enter your first name: '); print ('Your name is: ' + firstname + ' ' + lastname)

Answer 23

slight variation to ja9's work makes it more user friedly
What is your last name?
Doe
What is your first name?
John
Hello John Doe
print "What is your last name?";
lastname = raw_input();
print "What is your first name?";
firstname = raw_input();
print "Hello", firstname, lastname;

having the print before the raw_input makes it jump to the next line. the raw_input() means the line where they type there is nothing on it.

Answer 24

Nice. Also, @commando1200, keep in mind that you don't need semicolons on the end in Python -- you can just change lines. You only need semicolons if you're going to put two distinct statements on the same line, which is generally frowned upon in Python anyway.

Answer 25

This is what I did. I basically looked at the example in the problem set and just did that:

last = raw_input("What is your last name?\n")
first = raw_input("What is your fist name?\n")

print first
print last

Answer 26

I'm having trouble running my program. I wrote the code in IDLE and when I enter the last line (e.g. >>>print 'Hello', firstname, lastname) I get the correct response. But when I try to open the program in Python Launcher, i get an error saying invalid syntax. Can anyone offer any advice?

Answer 27

Hm. Can you give us the full error message? It should have more details which will help in determining what is going on.

Answer 28

kevins-macbook-pro-15:~ kevin$ cd '/Users/kevin/Desktop/' && '/usr/local/bin/pythonw' '/Users/kevin/Desktop/ps0try.py' && echo Exit status: $? && exit 1

Answer 29

And what are the contents of the file?

Answer 30

>>> print 'What is your last name? '
What is your last name?
>>> lastname=raw_input()

>>> print 'What is your first name? '
What is your first name?
>>> firstname=raw_input()

>>> print 'Hello', firstname, lastname
Hello

Answer 31

Ah ha! I figured it out. The >>> symbols shouldn't be in the saved file. So the new question is how do I save a file in IDLE so that the text file doesn't contain the greater than signs?

Answer 32

Hi guys, I just started on this class and I'm a bit overwhelmed by it. Anyway, can I just chip in and ask if my answer to PS0 is right? Or is the some other way I should write it in?

answer1 = raw_input ('What is your last name?')
answer2 = raw_input ('What is your first name?')
print answer2, answer1

Answer 33

@k1e4v -- I believe IDLE has a File->New File or some such option that will let you open a new file in an editor. Then there will be a menu option that will let you run that file in the execution window where you've been typing until now.

@alexisthetiny -- Looks good to me! Might want to put a space after the question mark on the raw_inputs so that the user isn't typing immediately next to the question mark, though.

Answer 34

@shadowfiend, thanks! =)

Answer 35

No problem, glad to help!

Answer 36

If you like to be grammatically correct, then for the last line, do the following:
print "Your name is " + firstname + ' ' + lastname
:)
