I am having problems trying to remove substrings from a column that are contained within the string of another column:
df = pd.DataFrame(
{
"substring": ["This", "sentence."],
"id": [1, 1],
"string": ["This is a sentence.", "This is another sentence."],
}
)
df["replaced"] = df["string"].str.replace(df["substring"], "")
CodePudding user response:
Use list comprehension:
df["replaced"] = [x.replace(y, "") for x, y in zip(df["string"], df["substring"])]
print (df)
substring id string replaced
0 This 1 This is a sentence. is a sentence.
1 sentence. 1 This is another sentence. This is another
CodePudding user response:
Or using apply paradigm
df['replaced'] = df.apply(lambda row:row['string'].replace(row['substring'],''),axis=1)
