Python程序不起作用-非常简单

Question

Basically for this assignment I need to convert a name into a 'secret number' by summing the value I assigned each letter. Everything works so far but when I try to sum it up it gives me an error. I think I need to convert the letters into their number form but everything i've tried so far won't work.

eg

total_name =0 for c in end_name
    c_int = int(c)          
    total_name+= c_int

Any help would be greatly appreciated! Here's my code:

'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'==10
'u'==21
'v'==22
'w'==23
'x'==24
'y'==25
'z'==26

#input:ask user to enter their name
#processing: convert name into all lower case then calculate number
#output: return name and reduction to user

name = input('Name:')
new_name= str.lower(name)
end_name=new_name.replace(" ","")

print('Your "cleaned up" name is:',end_name)

total_name =0
for c in end_name

    total_name+= c

print('Reduction:',total_name)

for c in end_name:

Answer 2

You will need the ord() function to convert a character into a number.

The ASCII code for 'A' is 65, so you could subtract 64 to scale to your preferred offset.

total_name=0
for c in end_name:
    total_name+=ord(c)-64

For lowercase, 'a' is ASCII code 97, but then you'd get negative numbers for any uppercase. You could just as well normalize the entire string to uppercase (or lowercase, your choice) before the loop.

Answer 3

Here is one approach:

values = dict(zip("abcdefghijklmnopqrstuvwxyz", range(1,27)))
name = raw_input('Name:')
score = 0

for l in name.lower():
    score += values[l]

For the input Jason I get the value 59

Answer 4

_d = {chr(k): k for k in range(97, 123)}

inp = raw_input().replace(" ", "").lower()

print ''.join([str(_d[ele]) for ele in inp])

Or use sum if you want as sum

print sum([str(_d[ele]) for ele in inp])

Output:

as d f g

Answer 5

This problem can be done in two lines:

name = input('Name: ').lower().replace(" ", "")
print(sum(ord(letter) - ord('a') + 1 for letter in name))
