这种情况下, 像 pybind11, boost.python 等中间件应运而生, 而 pybind11 对比实现复杂度和依赖都非常重的 boost.python, 显然更有优势, 功能实现和特性上 pybind11 也更占优, 落差从GitHub上两个库的热度就能看出来了: ===2016年 pybind11 cppconn 演讲时的数据=== ===到2023年4月, 本文写作的时间, ...

# Another way to call functions is with keyword arguments add(y=6, x=5) # Keyword arguments can arrive in any order. 可以在参数名之前加上*表示任意长度的参数,参数会被转化成list: # You can define functions that take a variable number of # positional arguments def varargs(*args): return ...

Tcl's syntax is similar to many shell languages, where the first word is the command to be executed, with arguments to that command following it, separated by spaces. Without getting into too many details, notice the following: The commands used to create widgets (like ttk::frame) correspond...
Pandas will try to call date_parser in three different ways, # advancing to the next if an exception occurs: 1) Pass one or more arrays # (as defined by parse_dates) as arguments; 2) concatenate (row-wise) the # string values from the columns defined by parse_dates into a single ...
1、list can hold arbitrary objects and can expand dynamically as new items are added. A list is an ordered set of items. 2、A tuple is an immutable list. A tuple can not be changed in any way once it is created. 3、A set is an unordered “bag” of unique values. A single set ...
