本文实例讲述了Python3实现从指定路径查找文件的方法。分享给大家供大家参考。具体实现方法如下:
这里给定一个搜索路径,根据这个路径请求和请求的文件名,找到第一个符合要求的文件
import os def search_file(file_name, search_path, pathsep = os.pathsep): for path in search_path.split(pathsep): candidate = os.path.join(path, file_name) if os.path.isfile(candidate): return os.path.abspath(candidate) return None search_path = 'd:\\pm\\pm' find_file = search_file('babyos.img', search_path) if find_file: print("File 'babyos.img' found at %s" % find_file) else: print("File 'babyos.img' not found")
希望本文所述对大家的Python3程序设计有所帮助。

Mathematical operations of the entire array in NumPy can be efficiently implemented through vectorized operations. 1) Use simple operators such as addition (arr 2) to perform operations on arrays. 2) NumPy uses the underlying C language library, which improves the computing speed. 3) You can perform complex operations such as multiplication, division, and exponents. 4) Pay attention to broadcast operations to ensure that the array shape is compatible. 5) Using NumPy functions such as np.sum() can significantly improve performance.

In Python, there are two main methods for inserting elements into a list: 1) Using the insert(index, value) method, you can insert elements at the specified index, but inserting at the beginning of a large list is inefficient; 2) Using the append(value) method, add elements at the end of the list, which is highly efficient. For large lists, it is recommended to use append() or consider using deque or NumPy arrays to optimize performance.
