into the interpreter and are always available for use anywhere in your Python project or terminal without importing them.<\/p>\n\n\n\n<p>These predefined functions in Python are not specific to string only but may be applicable to other sequence types(<strong>list, tuple, set, dict, range<\/strong>) and even other data types.<\/p>\n\n\n\n<p>Don&#8217;t get overwhelmed, we are only going to talk about how the built-in functions can be used to manipulate strings.<\/p>\n\n\n\n<p>The table below demonstrates how some of the built-in functions in Python are used on strings.<\/p>\n\n\n\n<p>Python
