Python String replace() Method

​The replace() function returns a new copy of the string in which all occurrences of the substring are replaced by another substring. It can also specify how often substrings should be replaced by another substring.

Example of using the replace() function: This function can be used to replace multiple similar misspellings in any document at once.

string. replace(old, new, count)

In the following example we will replace one character from a given string. Note that the replace() function is case sensitive so the letter A in Ahmed remains unchanged.

Example:

string = "Ahmed obaid"  
# replace all instances of 'a' (old) with 'e' (new
new_string = string.replace("a", "e" )
print(string)
print(new_string)

 The output will be:

Ahmed obaid
Ahmed obeid

 In the following example, we will replace the word python in the old string with the word django in the new string

 Example:

string = " learn  python  with ahmed obaid"  
# replace all instances of 'python' (old) with 'django' (new)
new_string = string.replace("python", "django" )
print(string)
print(new_string)

 The output will be:

learn  python  with ahmed obaid
 learn  django  with ahmed obaid

 In the following example we will replace a certain number of characters. i.e. "x" with "a" with number = 2 .

string = " learn  python  with ahmed obaid"  
# replace all instances of 'a' (old) with 'x' (new)
new_string = string.replace("a", "x" , 2)
print(string)
print(new_string)

 The output will be:

 learn  python  with ahmed obaid
 lexrn  python  with xhmed obaid

 Notice in the previous example that the letter a in the word obaid has not changed. Because we have limited the number of replacements allowed. It is 2 times
