Python: os.path.basename 无后缀文件名称

import os


def custombasename(fullname):
    return os.path.basename(os.path.splitext(fullname)[0])


a = 'var/label/txt/123.txt'
print(custombasename(a))

print(os.path.splitext(a))
print(os.path.splitext(a)[0])
print(os.path.basename(os.path.splitext(a)[0]))  # 取1个path的最后名称

# 同理，先取最后文件名，再得到无后缀名称
print(os.path.basename(a))
print(os.path.splitext(os.path.basename(a))[0])

('var/label/txt/123', '.txt')
