Since we passed 1, only the first occurrence ( from left) of the old substring be was replaced by the new substring code and all the other occurrences were unchanged in the returned string.įor more on python string replace function, refer to the python docs. This argument controls the number of replacements to be made. In the above example, we pass the third argument to the replace function. In the above example, since the value passed for the old parameter, was is not present in the string, a copy of the original string without any replacement is returned.Įxample 3: Replacing only a fixed number of occurrences. Output: Original string: to be or not to be In the above example, all the occurrences of the underscore symbol, _, have been replaced by a single space, ' ', in the returned string.Įxample 2: When the substring to be replaced is not present s = "to be or not to be" Output: Original string: to_be_or_not_to_be ExamplesĮxample 1: Replace all the occurrences of underscores _ with a single space ' '. Note: If the value passed for the old parameter is not found, a copy of the original string without any change is returned. If it’s not provided, all the occurrences of the old substring are replaced by the new substring.Ī copy of the original string with occurrences of the old substring replaced by the new substring. count ( optional): The number of times you want to replace the occurrence of the old substring with the new one.To replace one or more occurrences of a character/substring from the original string with the new character/substring, we have to use python's string replace () function. New: This is the new text that the function would substitute for the old original one. new: The new substring you want to replace the old substring with. In python, there is a replace () function which help to update the old value (character/substring) with a new value (character/substring). Python String replace Old: Specify the sentence that you want to change.The following is the syntax to use the python string replace function, replace(): str.replace(old, new, count) It is an inbuilt string function that returns a copy of the string where occurrences of the original substring have been replaced by the new substring. In python, the string replace function, replace(), is used to replace the occurrences of a substring with a different substring.
