This article mainly explains "how to read file names by python". Friends who are interested may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to read file names by python".

The operating environment of this tutorial: windows7 system, Python 3.9.1 Dell G3 computer.

1. The os.listdir () function only gets the file name under the current path, excluding the file in the subdirectory, and needs to get the file name recursively.

# returns all files under the specified path, excluding subdirectories. Path2 = r "C:\ Users\ 11764\ Desktop\ Data" f = os.listdir (path2) print (f) output: ['2020-09-16,' 2020-10-11, 'baidu_index_0625.xlsx',' city_id.xlsx', 'city_index_0625.xlsx',' province_id.xlsx', 'province_index_0625.xlsx']

2. The os.path.splitext () function splits the path into a file name and an extension (suffix).

The result of os.path.splitext (svm.model) [0] is that svm makes a decision on all the file names, and then adds them to the corresponding list.

Import os# saves directory names of different models (absolute path) file_dir = ritual C:\ Users\ zhangyh5\ Desktop\ xietong1012\ model'bayes_list = [] # Bayesian model list svm_list = [] # svm model list xgboost_list = [] # xgboost model list # root refers to the current directory path (the absolute path to the folder) # dirs refers to the subdirectories under the path ( The folder in the folder) # files refers to all the files under the path (all the files in the folder) for root Dirs,files in os.walk (file_dir): for file in files: if os.path.splitext (file) [0] = 'bayes': bayes_list.append (os.path.join (root,file)) elif os.path.splitext (file) [0] =' svm': svm_list.append (os.path.join (root) File)) elif os.path.splitext (file) [0] = 'xgboost': xgboost_list.append (os.path.join (root,file)) so far I believe you have a deeper understanding of "how to read file names from python", so you might as well do it in practice.
