dictionary - Python throws SyntaxError on this code -

while 1:     dic = {} #empty dictionary used storing data     dic[raw_input("enter value want store: ")]  = input("enter access key of value: ")     ans = raw_input("exit:e ; store variable : s; acces variable: a")     if ans=="e":         break; #exit main loop     elif ans == "s":         continue;     elif ans=="a":         pass; 

please help

you using input() instead of raw_input(); interprets input python expression. easy make throw syntaxerror exception:

>>> input("enter sentence: ") enter sentence: quick brown fox traceback (most recent call last):   file "<stdin>", line 1, in <module>   file "<string>", line 1     quick brown fox             ^ syntaxerror: invalid syntax 

use raw_input() throughout instead:

dic[raw_input("enter value want store: ")]  = raw_input("enter access key of value: ") 

you want turn these 2 questions around:

dic[raw_input("enter access key of value: ")] = raw_input("enter value want store: ") 

python ask value first. if need ask key first, store in separate variable first:

key = raw_input("enter access key of value: ") dic[key] = raw_input("enter value want store: ")
