# argparse

```python
import argparse

# ArgumentParser
parser = argparse.ArgumentParser()
parser.add_argument('-all', action="store_true")
parser.add_argument('-task', help='==> your task')
parser.add_argument('-file', help='==> file path')

args = parser.parse_args()

```

```
設定action="store_true"，表示若使用該參數時則帶入True
#python test.py -c => c是true（觸發）
#python test.py => c是false（無觸發）
```
