How to Replace a String in Python
- Replacing strings in Python is a fundamental skill. You can use the .replace() method for straightforward replacements, while re.sub() allows for more advanced pattern matching and replacement.
- You can replace parts of a string by chaining .replace() calls or using regex patterns with re.sub().
- You replace a letter in a string by specifying it as the first argument in .replace().
- You remove part of a string by replacing it with an empty string using .replace() or re.sub().
- You replace all occurrences of substrings in a string by using .replace().
