根据列中特定字符“+”的存在过滤 dataframe 的行

Question

I have data frame like this:

id : Name 
0  : one
1  : one + two
2  : two
3  : two + three + four

I want to filter rows from this dataframe where name contains '+' and save it to another dataframe. I tried:

df[df.Name.str.contains("+")]

but i'm gettin error:

nothting to repeat at position 0

Any help would be appreciated...Thanks

Looking at the documentation of the str.contains method, it assumes that the string you are passing is a regexp by default.

Therefore, you can either escape the plus character: "\+" or pass the argument regex=False to the method:

• df[df.Name.str.contains("\+")]
• df[df.Name.str.contains("+", regex=False)]
