We used a while loop to iterate for as long as the start variable is less than the string's length. On each iteration, we use the str.find() method to find the next index of the substring in the string. The str.find method returns the index of the first occurrence of the provided...
Thefind()method returns the index of first occurrence of the substring (if found). If not found, it returns-1. Example message ='Python is a fun programming language' # check the index of 'fun'print(message.find('fun')) # Output: 12 Run Code find() Syntax The syntax of thefind()me...
# returns first occurrence of Substring result=word.find('geeks') print("Substring 'geeks' found at index:",result) result=word.find('for') print("Substring 'for ' found at index:",result) # How to use find() if(word.find('pawan')!=-1): print("Contains given substring ") else:...
1. UsingindexOf()method The idea is to use theindexOf()method of theStringclass, which returns the index within this string of the first occurrence of the specified substring, starting at the specified index. It returns-1if there is no such occurrence. ...
5.If sub-string not find in the string then it returns -1Example:# Python program to explain find() method sstr = 'Welcome to STechies: Smart Techies' # Returns first occurrence of Substring sub = sstr.find('STechies') print ("Stechies is at :", sub ) # find() method is case...
The find() is a built-in method in Python that searches for a substring in a string. It returns the index of the first occurrence of the substring or -1 if not found. It holds: The substring argument is required and used to search it in the given string. The start and end arguments...
"python", "at", "includehelp" A simple method to solve the problem is by finding words that occur only once in any of the strings. For this, we will create a hashmap by which will store the words and their frequency of occurrence for both strings. And then print those words from th...
Python program to find the ASCII value of each character of the string # initialize a strings='Motihari'ascii_codes=[]# to contain ASCII codes# getting ASCII values of each character# using ord() method and appending them# to "A"foriinrange(len(s)):ascii_codes.append(ord(s[i]))# ...
python script.py somefile.in somefile.out To replace thefirstoccurrence of a pattern with a given string, use${parameter/pattern/string}: #!/bin/bash firstString="I love Suzi and Marry" secondString="Sara" echo "${firstString/Suzi/$secondString}" ...
The syntax of the method is: str.find(s, sub[, start[, end]]) Key Points : • If the string contains a substring, this function returns the index for the first string occurrence; if the substring does not exist in a string, the function returns -1. ...
