# glob.glob()

返回所有匹配的文件路径列表。它只有一个参数pathname，定义了文件路径匹配的规则，可以是绝对路径，也可以是绝对路径，也可以是相对路径。查找文件只用到三个匹配符：*，？，[]。`*` 可以匹配0个或多个字符；`?` 匹配单个字符；`[]` 匹配指定范围内的字符。

```python
import glob

#获取指定目录下的所有图片
print(glob.glob(r"/home/wang/*/*.png"))
```

# glob.iglob()

 返回一个生成器对象，匹配pathname的参数，与glob.glob()的区别是：glob.glob同时获取所有的匹配路径，而glob.iglob一次只获取一个匹配路径。

```python
import glob

f = glob.iglob(r"../*.py");
print(f)#<generator object iglob at 0x00B9FF80>
for py in f:
    print(py)
```
