In this chapter let us create a few examples with Python built-in RegEx module’s methods and see what this particular module can do!<\/p>\n
As always, you need to import the module into your python file before using it.<\/p>\n
\r\nimport re\r\n<\/pre>\nFind whether a phrase is contained within a string or not and uses case insensitive search.<\/p>\n
\r\ntext = "Well, again, it is Hello WORLD!..."\r\nresult = (re.match(".*Hello World.*", text, re.I))\r\n<\/pre>\nBelow is the return Match object.<\/p>\n
\r\n<re.Match object; span=(0, 34), match='Well, again, it is Hello WORLD!...'>\r\n<\/pre>\nWhich shows it matches our search.<\/p>\n
Besides using to search a string, re module also can be used to split the text into a list. The below line will split the text into a list at each white-space character.<\/p>\n
\r\ntext = "Well, again, it is Hello WORLD!..."\r\nresult = re.split("\\s", text) # ['Well,', 'again,', 'it', 'is', 'Hello', 'WORLD!...']\r\n<\/pre>\nAt last, let us replaced hello world with a good morning phrase.<\/p>\n
\r\ntext = "Well, again, it is Hello WORLD!..."\r\nresult = re.sub("Hello WORLD", "good morning", text) # Well, again, it is good morning!...\r\n<\/pre>\nThere is still more to learn from this module which I will leave to you all to explore by yourself.<\/p>\n","protected":false},"excerpt":{"rendered":"
