將python dict或csv文件轉換爲數據幀

Question

我有一個字典轉儲爲csv，如下所示。我如何將它轉換爲數據框 X，Y，SN作爲頭文件？我正在考慮寫一個for循環和利用拆分 但它似乎犯規很優雅，也沒有效率......

不要使用for循環，增加行到現有的數據幀是不是很有效。

def split(string): 
    return string.split(',', 1) 

df = pd.read_csv(file_path, header=None, names=['Cord', 'SN']) 
df['X'], df['Y'] = zip(*df.Cord.map(split)) 
df = df[['X', 'Y', 'SN']]
