Python去除文件中的空格、Tab键和回车

def stripFile(oldFile, newFile):
    '''remove the space or Tab or enter in a file, and output a new file in the same folder'''
    f = open(oldFile, 'r+', encoding='utf8')
    newf = open(newFile, 'w',encoding='utf8')
    for eachline in f.readlines():
        newStr = eachline.replace(" ", "").replace("\t","").strip()
        newf.write(newStr)
    f.close()
    newf.close()

if __name__ == "__main__":
    stripFile("lc_iocapp.postman_collection.json",'lc_iocapp.postman_collection_new.json')

去除文件中的空格、tab和回车，重新生成一个新文件。

如有更好的方法，请各位大虾不吝赐教！
