2. Check String is Empty using len() The Pythonlen()is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, thelen()function returns the length of an object. The object can be a string...
Return a list of the words in S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator and empty strings are removed from the result. s='2018-11-02' s.split('-') 1....

This is unrelated to the earlier rule on==vsisforNone. In this case, we are actually taking advantage of Python's "truthiness rules" to our benefit inif item, e.g. as a shorthand "item is not None or empty string." Truthiness is atad complicatedin Python and certainly the latter is...

By default, the separator is any whitespace, but it can be specified otherwise. Python Concatenate Strings The + operator is used to add or concatenate a string to another string a = “Python tutorial” b = “ by Intellipaat” c = a + b print(c) The output will be: Python tutorial...
To remove whitespace or specific characters from the ends of a string: s = " trim me " print(s.strip()) # Both ends print(s.rstrip()) # Right end print(s.lstrip()) # Left end 6. String Methods — startswith, endswith To check the start or end of a string for specific text:...
Whitespace is like the"empty space"in our data. It might not seem like much, but in programming and data analysis, it can often lead to errors, incorrect results, or simply make data harder to read and analyze. That's why it's important to understand how to manage and control whitespac...
int PySequence_Check(PyObject *o)如果对象提供序列协议,则返回1,否则返回0。请注意,对于具有__getitem__()方法的 Python 类,除非它们是dict子类[...],否则它将返回1。我们期望序列还支持len(),通过实现__len__来实现。Vowels没有__len__方法,但在某些情况下仍然表现为序列。这对我们的目的可能已经足够了...
