Question

This is a very dumb question but I am doing something wrong and I am not sure what it is. I am on the very first problem set and I am having a hard time with the "raw_imput()" code. Everytime I use this code it returns with:

"Traceback (most recent call last):
File "", line 1, in answer=raw_imput() NameError: name 'raw_imput' is not defined" I know this is something simple.

Answer 1

I am using version 2.5.4 which is the suggested version for the class. Also, I have tried "imput()" and receive the same error.

Answer 2

raw_iNput()

Answer 3

Wow, thanks. I guess you need someone to slap you upside the head every once in awhile to let you know you are making a simple error. Thanks again.

Answer 4

Hello, world! I am back. Hopefully, this question is not as dumb. So my understanding of creating a program is to create the file using a text editing program (text edit, text wrangler, etc), type in the code and save it as a ".py" file. My understanding of running the program is to change the directory to the folder where the ".py" file is located. Now, the problem I am running into is when I type in "cd pythonpractice" (pythonpractice is the name of the folder where my hello,py file is stored) is that it will return with a syntax error:

>>> cd pythonpractice
SyntaxError: invalid syntax

I have saved the "python practice" folder in the home directory so I am not sure what I am doing wrong here…Please help!

Answer 5

you need to go to the home directory first, type "dir" in the command line to show the current file/folders in the directory you are in

Answer 6

>>> dir
<built-in function dir>

that is what I get.

Just to correct what I said earlier, not the home directory but the home folder.

Answer 7

so you are in the folder where the .py in?

Answer 8

This is what I have been following: http://en.wikibooks.org/wiki/Python_Programming/Creating_Python_Programs

Answer 9

I try to go to the folder where the file is in by typing:

>>> cd pythonpractice

Answer 10

ok, so you are in C:\ and your folder is there

Answer 11

I try, but I get a syntax error. Also I am following the mac directions.

Answer 12

what do you get if you type "pwd" ?

Answer 13

Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
pwd
NameError: name 'pwd' is not defined

Answer 14

In terminal or IDLE?

Answer 15

terminal

Answer 16

/Users/Anthony

Answer 17

for terminal

Answer 18

and do you know where is your pythonpractice folder located?

Answer 19

same as above

Answer 20

type "ls" and see if your folder is there

Answer 21

when i type that it shows in terminal

Answer 22

ok try to cd to it again make sure you dont have a spelling mistake

Answer 23

haha yes I have a track record of poor spelling. However, that is not the case.

folder name from terminal when typing "ls" - pythonpractice (this is copied and pasted)

response when typing it into IDLE - >>> cd pythonpractice
SyntaxError: invalid syntax

Answer 24

type cd pythonpractice in the terminal

Answer 25

I dont know if this would make a difference but I am using version 2.5.4 which is the version used in the open courseware class from MIT

Answer 26

when typed into the terminal it says "Anthonys-MacBook-Pro-2078:pythonpractice Anthony$"

Answer 27

i don think the version is the issue, been while since i used idle and i dont know much about it, but you should type cd pythonpractice in terminal instead

Answer 28

great now type ls what do you get ?

Answer 29

it shows the file labeled "hello.py"

Answer 30

now type "python hello.py"

Answer 31

It printed "Hello, world!"

Fantastic! So is IDLE used more for testing the strings?

Answer 32

idle used to write the code, and you run it in the terminal, i think your mistake was that you trying ti cd in idle instead of the terminal, there are other application that let you code and run the application with just one click, i dont know what your course using other than idle but in mac i recommend using pycharm

Answer 33

Great! Thanks!

Are you taking this course as well?

Answer 34

no i studied python in school in my first year

Answer 35

That is great, a good thing to learn in school. Unfortunately for me I earned a degree that is not really helping me lol so I have to go back and learn this stuff.

Thank you again for your help.

Answer 36

no problem, python is really easy to learn and you dont really need school to learn everything, there are alot of good resources online, either courses like mit or videos on youtube. Good luck!
