As usual, Python favors readability by using English words as operators instead of potentially confusing symbols or combinations of symbols. Note: The syntax not value in collection also works in Python. However, this syntax looks odd and is difficult to read. So, to keep your code clean and...
0、In Python 2, the / operator usually meant integer division, but you could make it behave like floating point division by including a special directive in your code. In Python 3, the / operator always means floating point division.
default string encoding. errors may be given to set a different error handling scheme. The default is 'strict', meaning that encoding errors raise UnicodeError. Other possible values are 'ignore', 'replace' and any other name registered via codecs.register_error(), see section Codec Base ...

Although all of these looping patterns are supported by Python, we should be careful when using them.Because most loops are evaluated in a piece-by-piece manner, they are often inefficient solutions. We should try to avoid looping as much as possible when writing efficient code. Eliminating loo...
