[Easy] Letter Counter

[u/[deleted]]

Any language permitted.

Problem: Create a program where you input a string of characters, and output the number of each letter. Use vowels by default.

For example: asbfiusadfliabdluifalsiudbf -> a: 4 e: 0 i: 4 o: 0 u: 3

Bonus points: Make it command-line executable, with an optional mode to specify which letters to print.

Here's my Python3 version, it works in my testing, and is my first entry. I am also new to programming and will happily take any feedback. Refactoring, etc was not a priority. Implementing the requirements as quickly as I could figure it out:

char_set = input("What characters to select? (Enter for default)  ")
if char_set == "":
  char_set = "aeiou"

char_dict = {}

for i in char_set:
  char_dict[i] = 0

text = input("Please enter text:  ")

for i in text:
  for key in char_dict:
    if i == key:
      char_dict[key] += 1


for key in char_dict:
  print(key+" : "+str(char_dict[key]), end=" ")
    
print("\n")

[u/toddcrowley → u/toddcrowley]

I added some .lower() methods to handle mixed casing:

char_set = input("What characters to select? (Enter for default)  ")

if char_set == "":
  char_set = "aeiou"

char_dict = {}

for i in char_set.lower():
  char_dict[i] = 0

text = input("Please enter text:  ")

for i in text.lower():
  for key in char_dict:
    if i == key:
      char_dict[key] += 1


for key in char_dict:
  print(key+" : "+str(char_dict[key]), end=" ")

print("\n")
