Write a python program to find the first non repeating character in given string
In this article, we will find the first non-repeating character from a stream of character. Let’s say the following is our input − Show Thisisit The following should be our output displaying first non-repeating character − H Find the first non-repeating character from a stream of characters using while loop We will find the first non-repeating character, by comparing each character with the other using a loop − Example
OutputNo Unique Character Found! First non-repeating character = h Find the first non-repeating character from a stream of characters using a function We can also create a custom function and pass the string to it for finding the first non-repeating character − Example
OutputFirst Non-Repeating Character = h Find the first non-repeating character from a stream of characters using Counter() The Counter can also be used from the Collections module to find the first non-repeating character. This module implements specialized container datatypes providing alternatives to Python’s general purpose built-in containers, dict, list, set, and tuple − Example

How do you get the first non repeated character in a string in Python?"": slen0 = len(myStr) ch = myStr[0] myStr = myStr. replace(ch, "") slen1 = len(myStr) if slen1 == slen0-1: print ("First non-repeating character = ",ch) break; else: print ("No Unique Character Found! ")
How do you find the non repeated character of a given string?Using the indexOf() and lastIndexOf() method, we can find the first non-repeating character in a string in Java. The method indexOf() returns the position of the first occurrence of a given character in a string whereas method lastIndexOf() returns the position of the last occurrence of a given character in a string.
