Replace All Instances of a Single Character using replace()In this example, we are only replacing a single character from a given string. The Python replace() method is case-sensitive, and therefore it performs a case-sensitive substring substitution, i.e. R in FOR is unchanged. Python3
Output : grrks FOR grrks geeks FOR geeks Replace All Instances of a StringHere, we replaced all the geeks with GeeksforGeeks using replace() function. Python3
Output : geeks for geeks geeks for geeks GeeksforGeeks for GeeksforGeeks GeeksforGeeks for GeeksforGeeks Replace Only a Certain Number of Instances using replace()In this example, we are replacing certain numbers of words. i.e. “ek” with “a” with count=3. Python3
