本文介绍了Python lambda:TypeError:类型' float'的参数是不可迭代的的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我试图将 df ['matrix']
中的信息提取到四个新列中. df ['matrix']
看起来像这样:
I was trying to extract information from df['matrix']
into four new columns. The df['matrix']
look like this:
id matrix
0 {'status': 'ZERO_RESULTS'}
1 {'distance': {'text': '3,899 km', 'value': 3898595}, 'duration': {'text': '1 day 13 hours', 'value': 133445}, 'status': 'OK'}
2 {'distance': {'text': '2,065 km', 'value': 2065157}, 'duration': {'text': '20 hours 7 mins', 'value': 72393}, 'status': 'OK'}
我的代码:
df['dist_value'] = df['matrix'].apply(lambda x: round((x['distance']['value']) / 1000) if "status" not in x else None)
df['dist_text'] = df['matrix'].apply(lambda x: x['distance']['text'] if "status" not in x else None)
df['duration_value'] = df['matrix'].apply(lambda x: float("%.2f" %((x['duration']['value'])/60/60)) if "status" not in x else None)
df['duration_text'] = df['matrix'].apply(lambda x: x['duration']['text'] if "status" not in x else None)
我收到以下错误:
df['dist_value'] = df['matrix'].apply(lambda x: round((x['distance']['value']) / 1000) if "status" not in x else None)
TypeError: argument of type 'float' is not iterable
推荐答案
由于您要检查状态"是否在x中,因此有时x不是字符串.您可以使用str(x)将x转换为字符串.
Since you are checking if "status" is in x and it looks like sometimes x is not a string. You can cast your x to string with str(x).
希望它能解决您的问题.
Hope it will solve your problem.
