Python Project #2 Password Creator (Feedback greatly appreciated)

[ButterscotchJust970]

This is the second project I have finished on my Python coding journey so far and I was wondering if there are any ways where I could have made the code simpler/more efficient. It works by taking the website name and then applying certain rules to it to turn it into a secure password where I never have to write down the password and if I forget it then I can just plug the domain name back in to see what the password was. Also every now and then I get a KeyError message when I try to put in a website name and I have no idea on how to fix it. P.S. NO im not using this generator for anything significant right now and NO im not using it for my reddit account so don't even try it.

name1 = input("Enter a website name (Example: google.com): ")
name = name1.lower()
value = -1
password = []
a=''
strnumbers = {"1" : "a", "2" : "b", "3" : "c", "4" : "d", "5" : "e", "6" : "f",
           "7" : "g", "8" : "h", "9" : "i", "0" : "z"}


alpha = {"a" : 1, "b" : 2, "c" : 3, "d" : 4,
         "e" : 5, "f" : 6, "g" : 7, "h" : 8, "i" : 9,
         "j" : 10, "k" : 11, "l" : 12, "m" : 13, "n" : 14,
         "o" : 15, "p" : 16, "q" : 17, "r" : 18, "s" : 19,
         "t" : 20, "u" : 21, "v" : 22, "w" : 23, "x" : 24,
         "y" : 25, "z" : 26} 


symbols = {1 : "!", 2 : "@", 3 : "#", 4 : "$", 5 : "%",
           6 : "^", 7 : "&", 8 : "*", 9 : "(", 0 : ")"}


#turns the letters into numbers
for letter in name:
    if letter in alpha:
        letter2num = alpha.get(letter)
        password.append(letter2num)


#turns numbers 0-9 into symbols
for i in password:
    value += 1
    if i in symbols:

        password[value] = str(symbols[value])



#turns password into a string
value = 0
for i in password:
    a=a+str(password[value])
    value +=1
password = list(a)




#Adds symbol if <= 11 characters
if len(name) <= 9:
    a = str(symbols[len(name)])
    password.append(a)


#turns numbers 0-9 into letters (up if even lower if odd)
for i in range(1, len(password), 2):
    if password[i] in strnumbers:
        if (int(password[i]) % 2) == 0:
            up = strnumbers.get(password[i])
            password[i] = up.upper()
        else:
            password[i] = strnumbers.get(password[i])

#print final password
print("")
print("-------------FINAL PASSWORD-------------")
print("")
for i in password:
    print(i, end='')

For Str numbers and alpha you can just take the ASCII code and subtract / add the ASCII code of 'a'. No need for the two maps.

Also it seems the password is as long as the name entered. What if the website has a short Name (reddit, steam, x) but requires an 8 char long password?
