I have a list:

lst = ['cat', 'cow', 'dog']

Need to print:

A1 cat
B2 cow
C3 dog

How I can do it?

    Read about loops and how to iterate over lists in Python. What did you try? What problems did you run into? – Omer Tuchfeld Apr 01 '18 at 18:24

    `print("A1 cat\nB2 cow\nC3 dog")` solves this particular case, but is probably not very well generalizable. What are the `A1`,...,`C3` strings, how do they depend on the names of the animals? – Andrey Tyukin Apr 01 '18 at 18:25

Here is one way.

from string import ascii_uppercase
lst = ['cat', 'cow', 'dog']

for num, (letter, item) in enumerate(zip(ascii_uppercase, lst), 1):
    print('{0}{1} {2}'.format(letter, num, item))

# A1 cat
# B2 cow
# C3 dog

Explanation

  • Use enumerate for a numeric counter with optional start value of 1.
  • Use string.ascii_uppercase to loop upper case alphabet.
  • zip and loop through, using str.format to format your output.

One way to accomplish this would be to use ASCII values of the alphabets and increment it over every iteration of the loop.

ascii_char_code = 65
lst = ['cat', 'cow', 'dog']

for index, item in enumerate(lst):
    print(chr(ascii_char_code) + str(index) + ' ' + item)
    ascii_char_code += 1

The chr() function converts ASCII code to the corresponding character

You can try this simple enumerate approach :

lst = ['cat', 'cow', 'dog']

chr_s = list(map(chr,range(65,90)))

for i,j in enumerate(lst,1):
    print("{}{} {}".format(chr_s[i-1],i,j))

output:

A1 cat
B2 cow
C3 dog
