Hi everyone.

 

I have a question about some of the variables Python recognizes.  I'm not exactly new to programming in general but I've found it difficult to grasp some of the things that take place seemingly spontaneously in the Python language.  I want to write a small text based game so I just wet ahead and looked for tutorials to get the feel for it.  I'm having problems understanding what happened from line 17 to line 20 in this code.  I understand that the entire block from 17 downward prints what's in the list but I just don't see where the "i" comes from in the 17th line.  I also don't understand how "\t" was assigned to anything, it just seemed to materialize with no explanation.  There are gaps in my knowledge regarding this admittedly but I'm used to a traditional global/local variables being called explicitly before anything can be done with them.  If someone could break down those lines for me some more I'd really appreciate it.  Also, if there's an alternative way to write those lines I'd really like to know for future reference.

 

EDIT:  the "i" is just a commonly used variable referrin to ndices used in mathematics.  This should have been made clear but no harm done.  I got some sleep and figured out that the t was for tab, duh.  There are other similar abbreviations around as well.  Good luck to anyone else who had the same little issue!





 

import textwrap

description = "You are standing in a field. To the north of you are some mountains, " \
              "to the east of you is a forest, to the west of you is a cave, and to " \
              "the south of you is a valley."

print textwrap.fill(description)

# The list of choices available to the user.
choices = [
    "Go to the mountains",
    "Go into the forest",
    "Go into the cave",
    "Go to the valley"
]

for i in range(0, len(paths)):
    choice = choices[i]
    menu_item = i + 1
    print "\t", menu_item, choices
