如何在Python中从cwd中获取单个文件大小

import os

file_path = os.path.join(os.getcwd(), '文件名')

file_size = os.path.getsize(file_path)

def convert_size(size):
    # 1 KB = 1024 bytes
    # 1 MB = 1024 KB
    # 1 GB = 1024 MB
    units = ['bytes', 'KB', 'MB', 'GB']
    index = 0
    while size >= 1024 and index < len(units) - 1:
        size /= 1024
        index += 1
    return f"{size:.2f} {units[index]}"

file_size_formatted = convert_size(file_size)

import os

def convert_size(size):
    units = ['bytes', 'KB', 'MB', 'GB']
    index = 0
    while size >= 1024 and index < len(units) - 1:
        size /= 1024
        index += 1
    return f"{size:.2f} {units[index]}"

file_path = os.path.join(os.getcwd(), '文件名')
file_size = os.path.getsize(file_path)
file_size_formatted = convert_size(file_size)

print(f"文件大小为：{file_size_formatted}")
