The follow is function which contral users' input:

def inputbox(showstr,showorder,length):
    instr = input(showstr)  #The input function require users enter information,showstr is give  hint
    if len(indtr)!=0:
        # There're three ways of check :1 digit ,nolimits   2 letter     3  digit and has limit
        if showorder ==1:
            if str.isdigit(instr):  
                if instr ==0:   
                    print("\033[1;31;40m enter is zero,Please renter \033[0m") 
                    return "0"
                else:
                    return instr 
            else:
                print("Illegal input,renter please")
                return "0"
        if showstr ==2:
            if str.isalpha(instr):
                if len(instr)!= length:  # check the limit
                    print("Must "+str(length)+"alpha,renter please!")
                    return "0"
                else:
                    return instr
            else:
                print("Illegal inut,renter please")
                return "0"
        if showstr ==3:
            if str.isdigit(instr):
                if len(instr)!= length:
                    print("The input must be "+str(length)+" numbers,try again please ")
                    return "0"
                else:
                    return instr
