What is the python equivalent of strpos($elem,"text") !== false)
returns -1 when not found:
pos = haystack.find(needle)pos = haystack.find(needle, offset)raises ValueError when not found:
pos = haystack.index(needle)pos = haystack.index(needle, offset)To simply test if a substring is in a string, use:
needle in haystackwhich is equivalent to the following PHP:
strpos(haystack, needle) !== FALSE
Is python is really pretty that code using "in":
in_word = 'word'sentence = 'I am a sentence that include word'if in_word in sentence: print(sentence + 'include:' + word) print('%s include:%s' % (sentence, word))last 2 prints do the same, you choose.
