Python Program to Count Repeated Characters in a String

This article is created to cover program in Python, that count and prints total number of repeated characters available in a given string entered by user at run-time.

Count Total Number of Repeated Characters in a String

The question is, write a Python program to count total repeated characters available in a string entered by user. Here is its answer:

rChar = 0
rCharList = []
k = 0

print("Enter the String: ")
text = str(input())

textList = list(text)
tot = len(text)

for i in range(tot):
  if text[i] in textList:
    if text[i] not in rCharList:
      newText = text[i+1:]
      newTot = len(newText)
      for j in range(newTot):
        if newText[j]==text[i]:
          rChar = rChar+1
          rCharList.insert(k, text[i])
          k = k+1
          break

print("\nTotal Repeated Character(s): ")
print(rChar)

Here is its sample run:

Now supply the input say fresherearth.com as string and press ENTER key to count and print the number of repeated characters available in the given string:

Note - In the string fresherearth.com, the repeated characters are c, o, e, r

To format the output-looks of previous program in better way, then change the following code:

print("Enter the String: ")

with the statement given below:

print(end="Enter the String: ")

And then block of code given below:

print("\nTotal Repeated Character(s): ")
print(rChar)

with following statement:

print("\nTotal Repeated Character(s): " + str(rChar))

After changing these two codes or block of code, here is the new output look of sample run with user input fresherearth this time:
