(DSA)Letter_Frequency.py

# Letter Frequency
# 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.
#Ans:
n = input()
l = input()
c=n.count(l)
p= (c/len(n))*100
print(p," is frequency in percentage.")
