try: chars[char]+=1
except: chars[char]=1
for key, value in chars.items():
print("{} -> {}%".format(key, value/len(text)*100))

Answer 2

Thanks

Answer 3

what does
'for key, value in chars.items():' do.

And chars. items is not defined

Answer 4

It iterate through a dictionary (chars).
chars = {'a': 1}
key -> 'a'
value -> 1

Answer 5

Doesn't that mean it simply displays the percentage of every character? I want to be able to input the character and get an output of its percentage

Answer 6

Yes it prints every character's pourcentage. If you want to print only the input :
try: print(chars[input()]/len(text)*100)
except: print(0)

Answer 7

You are making a program to analyze text.
Take the text as the first input and a letter as the second input, and output the frequency of that letter in the text as a whole percentage.

Sample Input:
hello
l

Sample Output:
40

Explanation : The letter l appears 2 times in the text hello, which has 5 letters. So, the frequency would be (2/5)*100 = 40.
