Pandas-计算字符字段中逗号的数量 [英] Pandas - Counting quantity of commas in character field

问题描述

我有一个熊猫数据框，其中的一列填充有字符串，如下所示:

I have a pandas dataframe with a column filled with strings as is shown below:

   string_column
0  t,d,t,d,v,d
1  s,v,y,d
2  d,u,f

我想用字符串列中的逗号计数创建一个新列.我的预期结果如下:

I would like to create a new column with the count of commas in the string column. My intended outcome is below:

   string_column  comma_count
0  t,d,t,d,v,d    5
1  s,v,y,d        3
2  d,u,f          2

大熊猫是否有可以完成此任务的字符串读取方法?

Is there a string reading method to pandas that will accomplish this task?

谢谢
