Other methods give you information about the string itself. The methodcountreturns how many times a given substring appears within a string. The methodendswithreturns whether the string ends with a certain substring, whereas the methodstartswithreturns whether the string started with a substring: Ano...
Usingstring slicingyou can remove the substring from the string. For example, first, initialize a stringstringwith the value “Welcome To SparkByExamples Tutorial” and define a variablesubstr_to_removecontaining the substring you want to remove, which is"Tutorial"in this case. After that, find ...

Lower() converts a string to its lowercase variant. Replace(old,new) replaces the old occurrence of the substring old with the substring new. Find() reports the offset where the first occurrence of the substring occurs. >>> banner = “FreeFloat FTP Server” >>> print banner.upper() ...
Python can’t find the all-lowercase string "secret" in the provided text. Humans have a different approach to language than computers do. This is why you’ll often want to disregard capitalization when you check whether a string contains a substring in Python. You can generalize your ...
