1、Python向上取整、向下取整和四舍五入取整函数
>>> import math
>>> math.ceil(12.5)
13.0
>>> math.floor(12.5)
12.0
>>> round(12.5)
13.0
2、获取文件大小:os.path.getsize()
'''获取文件的大小,结果保留两位小数,单位为MB'''
def get_FileSize(filePath):
filePath = unicode(filePath,'utf8')
fsize = os.path.getsize(filePath)
fsize = fsize/float(1024*1024)
return round(fsize,2)
