I am trying to create a function that inputs a name and outputs a rank. what is the best way to crea-CodePudding

I am trying to create function that takes an input name and outputs a rank based on the order of the letters it has for example a=1 b=2

name = ab
rank = 3

import string

x = "richard"
y = "donald"
c = "Sam"
numbers = []


for i in range(1,27):
    numbers.append(i)

print(numbers)

alphabet_string = string.ascii_lowercase
alphabet_list = list(alphabet_string)

print(alphabet_list)

new_x = list(x)
new_y = list(y)
new_c = list(c)

zip_iterators = zip(alphabet_list,numbers)
dic = list(zip_iterators)

print(dic)

def rank(name):
    rank = 0
    for l in range(0,len(name)):
        for k,v in dic:
            if l == k:
                v  = rank
        print(rank)

rank(new_c)

but I failed so far

letter_rank = {letter:rank for rank, letter in enumerate(string.ascii_lowercase, 1)}

def rank(name):
    return sum(letter_rank.get(c, 0) for c in name.lower())

CodePudding user response：

You can just use the ascii_lowercase constant in the string module:

from string import ascii_lowercase

def rank(x):
    total = 0
    for char in x:
        if char in ascii_lowercase:
            total  = ascii_lowercase.index(char)   1
    return total

print(rank('abc'))

Output: 6

CodePudding user response：

You could use ascii_lowercase.index(letter) or create a dictionary to lookup the rank of a letter. (My example doesnt't include caps, but you could do so if you wish)

lookup with dictionary

from string import ascii_lowercase

alphabet_lookup = {letter:i 1 for i, letter in enumerate(ascii_lowercase)}

def rank(name):
    return sum(alphabet_lookup[c] for c in name.lower())


print(rank('baa')) # outputs 4

`str.index`

def rank(name):
    return sum(ascii_lowercase.index(c) 1 for c in name.lower())

CodePudding user response：

You can use ord() built-in function and list comprehension to create the function you need as follows:

x = "Villalobos Velasquez Santiago"

def fun(s):
    out = 0
    for i in s.lower():
        if i != " ":
            out  = (ord(i)-96)
    return out

print(fun(x))

Output:
