In this tutorial, you'll be examining a couple of methods to get a list of files and folders in a directory with Python. You'll also use both methods to recursively list directory contents. Finally, you'll examine a situation that pits one method against
在上面的示例中,我们首先创建了一个包含5个元素的列表my_list,然后使用get方法获取了第3个元素和索引超出范围的元素。可以看到,当索引在列表范围内时,get方法返回对应的元素值;当索引超出范围时,get方法返回None。 列表list的get方法流程图 下面是列表list的get方法的流程图示意图: Index in rangeIndex out of ran...
在Python中,要获得一个文件夹下的子文件名,可以使用os模块中的listdir函数。listdir函数可以返回指定路径下所有文件和文件夹的名称列表。 首先,需要引入os模块: importos 1. 然后,使用listdir函数获取指定文件夹下的所有子文件名: folder_path='path/to/folder'file_list=os.listdir(folder_path) 1. 2. 这样,fil...
def sourceStatic(path, exclude): # exclude list convert to lower exclude = list(map(lambda x:x.lower(), exclude)) files_size = 0 files_count = 0 for root, dirs, files in os.walk(path): for fileName in files: fname, fileEx = os.path.splitext(fileName) fileEx = (fileEx[1:]...
Let’s see how to retrieve the first index in our list!Example 1: Get First Element of List Using IndicesBefore getting into how to get the first index in my_list, it might be interesting to know how to get the first element in this list. The first index in my_list can be found ...
How to get the last n elements of a list in Python? Getting the last n elements of a list in Python. You can use the slicing operator [-N:], where N is the number of elements you want to retrieve from the end of the list....
This is the recommended way for all developers, even if you don’t often code in Python. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 $ git clone git://github.com/soimort/you-get.git Then put the cloned directory into your PATH, or run ./setup.py install to install you-get to...
In this example, the length of the listmy_listis computed, and it’s printed to the console. Use List Comprehensions and thelen()Function to Get the Shape of Nested Lists in Python In addition to determining the length of a flat (1D) list, we can also use thelen()function to determine...
To get the length of a list in Python, you can use the len(list) function. The len() function works similarly with other data structures, including tuples, sets, and dictionaries. The list's size is not fixed; the user can add or remove data to the list during execution time. The ...
Plus, it works for all the Python versions.Example:import os # Example file path file_path = "/home/user/documents/report.txt" # First, get the directory of the file directory_path = os.path.dirname(file_path) # Now, use basename to get the last directory name last_directory = os....
