control Append in loop python

Question

I have a csv file and am working on a custom dictionary function where I would like to append values by user input; but, it is appending multiple times.

Which keys are occurring is shown in image:1.

I just want to append only once and then, depending on user input, restart the loop.

Gender name appending multiple times:

def dict2(data):
    data1=data
    empty = {}
    print ("Column names at first row",data1[0])
    print ("Total number of columns found: ", len(data1[0]))
    x=int(input("Please enter KEY column no.: "))-1
    print("Working on:",data1[0][x]," Column")
    y = input("Does data contains headers? Enter 1 or 0 :")
    if y == "1":
        data1 = data[1:]
    z = (input("Do you want to sum unique key values? Enter 1 or 0 :"))
    if z == "1":
        for i in data1:
            if i[x] not in empty:
                empty[i[x]] = 1
            elif i[x] in empty:
                empty[i[x]] +=1
    if z == "0":
        print ("Column names at first row",data1[0])
        z0 = int(input("How many values to assign in KEY: "))
        for i0 in range (z0):
            z1 = int((input("Please assign a value to key, Enter Column number :")))-1
        for i in data1:
            if i[x] not in empty:
                empty[i[x]] = [1]
                empty[i[1]].append(i[z1])
            elif i[x] in empty:
                empty [i[x]][0]+=1
    def inner_func():
        zx = input("do u: ")
        if zx == "1":
            z1 = int((input("Please assign a value to key, Enter Column number :")))-1
        for i in data1:
            if i[x] not in empty:
                empty [i[x]][0]+=1
            elif i[1] in empty:
                empty[i[x]].append(i[z1])
        zx = input("do u: ")
        if zx == "1":
            return inner_func()
    inner_func()
    return empty```
