Whilesys.argvis a straightforward way to grab command-line arguments, it can get messy when you start dealing with multiple arguments, optional arguments, and flags. That’s where argparse comes in. Argparse: Simplifying Command-line Parsing ...
Python command line flags For passing things like -O or -S to Python, to your compiled program, there is a command line option name --python-flag= which makes Nuitka emulate these options. The most important ones are supported, more can certainly be added. Caching compilation results The C...
app.flags 使用全局变量 # 可以再命令行中运行也是比较方便,如果只写 python app_flags.py 则代码运行时默认程序里面设置的默认设置 # 若 python app_flags.py --train_data_path <绝对路径 train.txt> --max_sentence_len 100 # --embedding_size 100 --learning_rate 0.05 代码再执行的时候将会按照上面的...
name or flags - 选项字符串的名字或者列表,例如 foo 或者 -f, --foo。 action - 命令行遇到参数时的动作,默认值是 store。 nargs - 应该读取的命令行参数个数,可以是具体的数字,或者是?号,当不指定值时对于 Positional argument 使用 default,对于 Optional - - - argument 使用 const;或者是 * 号,表示...
The philosophy of this project is to generate the most specific regular expression possible by default which exactly matches the given input only and nothing else. With the use of command-line flags (in the CLI tool) or preprocessing methods (in the library), more generalized expressions can be...
