可以使用百度汉语来做。源码源代urlencode是网页网页汉字在url中的形式,它是操作汉字的utf-8编码各字节的十六进制值(以%为前缀)
例如“中国”编码后是%E4%B8%AD%E5%9B%BD
百度汉语可以直接以get方法来起调,只需要用参数wd传入要查的源码源代字或词即可。
对于字和词,网页网页ch551g源码百度汉语返回不同的操作页面,因此,源码源代使用一个if来做分支,引用文献要溯源码分别处理不同的页面。
因为要求不使用下载的包,那么,c 源码怎么变成exe就直接使用python内置的requests来做请求,捡出拼音用re简单处理一下就好。
这是没有处理多音字的,如果要多音字返回所有读音,那么第一个分支里写法要改一改,判断读音段落结束才返回读音列表,每个读音re.findall的结果要添加到读音列表
