Answer 1

def convertNo(var,has):
    var = str(var[5:])   #since starting 6 terms are fixed (900)
    ans = ""
    i = 0
    while i < len(var):
        for k,v in has.items():
            if var[i].upper() in v:
                ans += str(k)
        i+=1
    return(ans)

has = {
    1:[""],
    2: ["A","B","C"],
    3:["D","E","F"],
    4:["G","H","I"],
    5:["J","K","L"],
    6:["M","N","O"],
    7:["P","Q","R","S"],
    8:["T","U","V"],
    9:["W","X","Y","Z"],
    "-":["-"]
} #created a has map according to need

var = input("enter string")
res = convertNo(var,has)
print("(900)"+res)
