Python学习（一）：查找大文件

import os

s = "java"
p = "d:lw"
m = 1024 * 1024 * 1024

#查找文件名
def find_file():
    for root, dirs, files in os.walk(p):
        for f in files:
            if f.find(s) != -1:
                name = os.path.abspath(os.path.join(root, f))
                print(name)


#查找大文件
def find_max_file():
    for root, dirs, files in os.walk(p):
        for f in files:
            name = os.path.abspath(os.path.join(root,f))
            if os.path.getsize(name) > m:
                print(name+' '+str(os.path.getsize(name)/m)+'G')

#主程序
def main():
    #find_file()
    find_max_file()

if __name__ == '__main__':
    main()
