Python code: Find the frequency of each character in the string

In this article, we will discuss the concept of the Python code: Find the frequency of each character in the string

In this post, we are going to learn how to  find the frequency of  the each character of the given string in Python programming language

Program to find the frequency of  the each characters in the string

find the frequency of  the each character in the string -method 1

The program allows the user to enter a String and then it finds the frequency of the each characters in the given string

program 1

string=input("Enter the string ")
freq=[None]*len(string)

for i in range(0,len(string)):
  freq[i]=1
  for j in range(i+1,len(string)):
    if(string[i]==string[j]):
        freq[i]=freq[i]+1

        string=string[:j]+'0'+string[j+1:];

print("Character and their frequency");
for i in range(0,len(freq)):
    if(string[i]!=' ' and string[i]!='0'):
        print(string[i]+"="+str(freq[i]))

When the above code is executed, it produces the following result

Enter the string python
Character and their frequency
p=1
y=1
t=1
h=1
o=1
n=1

find the frequency of  the each character in the string -method 2

The program allows the user to enter a String and then it finds the frequency of the each character in the given string

Program 2

string=input("Enter the string: ")
str1=list(string)
strlist=[]

for j in str1:
    if j not in strlist:
       strlist.append(j)
       count=0

       for i in range(len(str1)):
         if j==str1[i]:
           count+=1
       print("{},{}".format(j,count))

When the above code is executed, it produces the following result

Enter the string: mypython
m,1
y,2
p,1
t,1
h,1
o,1
n,1
