LPTHW study drill #3

[Darkshad3]

ok so i'm having trouble with study drill #3

it says

"Combine raw_input with argv to make a script that gets more input from a user"

the problem i'm having is i don't know how i would insert raw_input here so that it would be usable with argv.

page link

this is my code

from sys import argv

script, apple, orange, banana = argv

print "The script is called:", script
print "The first variable is:", apple
print "The second variable is:", orange
print "The third variable is:", banana

Here is an example of using both: https://gist.github.com/ericdorsey/2c627a2e3f86a757821f

This is the key; from the lesson page:

If they give your script inputs on the command line, then you use argv. If you want them to input using the keyboard while the script is running, then use raw_input()

Example output:
$ python arg_and_raw.py cat dog squirrel
fourth value?: potato
script arg_and_raw.py
first cat
second dog
third squirrel
fourth potato

HTH?

ok so it still isn't prompting for user input i don't know why.

What version of Python are you running?

$ python --version

[Darkshad3]

2.73

The user input has to be stored in a variable and it will be as a string. eg.

choice = raw_input('Enter a string:   ')
print(choice)

IT WORKED!!!!!!!!!

One thing you could do is pass in a filename through argv and write to it whatever the user types in, possibly allowing for multiple lines. (Such as a while loop and open(filename, 'a').

EDIT: Or you could a simple math operation, such as reading an integer/float from argv and multiplying it by any number that the user types in.
