The main point here is greedy match and non-greedy match greedy match: matches as many characters as possible; non-greedy match: matches as few characters as possiblePython's regular match is a greedy match by defaultExample:>>> Re.match (r'^ (\w+) (\d*) $','abc123'). Groups () ('abc123',"')>>> Re.match (r'^ (\w+?) (\d*) $','abc123'). Groups () ('ABC','123')Expression 1:\w+ indicates matching letters or numbers or underscores or kanji and repeats 1 or more times, \d* means matching numbers

I. SlicingSlicing operations are similar to sublist in Java, which is to get a sub-listFor example l=[' Zhangsan ', ' Lisi ', ' Wangwu '] then l[0, 2] means to start at index 0, until index 2 (excluding 2), exactly 2 elements. If the first index is 0, you can also omit it.Below we create a 0-99 series: L = Range (100)1. Get the top 10 numbers: L[:10]2. Get the last 10 numbers: l[-10:] # The index of the first element of the countdown is-13. Get the top 11-20: l[10:20]4. Get the first 10 numbers

() accepts a configuration object that, in addition to the paths property mentioned previously, has a shim property that is specifically designed to configure incompatible modules. Specifically, each module defines (1) The exports value (the output variable name), indicating the name of the external invocation of the module, and (2) An array of deps that indicates the dependency of the module. For example, the plugin for jquery can be defined like this:Shim: { ' Jquery.scroll ': {deps: [' jquer
