If I do the following in python,
string = raw_input('Enter the value')
it will return
Enter the value
and wait until I enter something into the prompt.
Is there a way to retrieve/collect the input I entered in a variable string?
I would like to use the entered value in the following way :
if dict.has_key('string'):
print dict[string]
Note: I previously made the error of using raw_string but I meant to say raw_input
there's no raw_string function in python's stdlib. do you mean raw_input?
string = raw_input("Enter the value") # or just input in python3.0
print(string)
This is very confusing ... I'm not familiar with a raw_string function in Python, but perhaps it's application-specific?
Reading a line of input in Python can be done like this:
import sys
line = sys.stdin.readline()
Then you have that line, terminating linefeed and all, in the variable line, so you can work with it, e.g. use it has a hash key:
line = line.strip()
if line in dict: print dict[line]
The first line strips away that trailing newline, since you hash keys probably don't have them.
I hope this helps, otherwise please try being a bit clearer in your question.
Is this what you want to do?
string = raw_input('Enter a value: ')
string = string.strip()
if string in dict: print dict[string]
import readline provides a full terminal prompt to the raw_input function. You get control keys and history this way. Otherwise, it's no better than the sys.stdin.readline() option.
import readline
while True:
value = raw_input('Enter a value: ')
value = value.strip()
if value.lower() == 'quit': break
