提取特定字符后的部分字符串，并放置在新列中

Question

I have a df in which I want to strip a string up to a certain character and then create a new column out of it.

a
John/Smith

becomes

a       b
John    /Smith

Thanks.

Answer 1

Use str.split

Ex:

import pandas as pd
df = pd.DataFrame({"a": ["John/Smith"]})
df[["a", "b"]] = df["a"].str.split("/").apply(pd.Series)
print(df)

Output:

      a      b
0  John  Smith
