replace multiple string values with different values in a column (python)

Question

Here is a sample dataset:

ID	Description
1	he wants some epples
2	she bought 2kgs of bakana
3	he got nothing
4	she took potato and tomat

I wanted to replace it this way:

df['Description']= df['Description'].str.replace({'epples':'apples','bakana':'banana','tomat':'tomato'})

It returned error:

TypeError: replace() missing 1 required positional argument: 'repl'

What can I do to reach this result:

ID	Description
1	he wants some apples
2	she bought 2kgs of banana
3	he got nothing
4	she took potato and tomato

Answer 1

Try like this :

import pandas as pd

df = pd.DataFrame({'ID':[1,2,3,4], 'Description':['he wants some epples', 'she bought 2kgs of bakana', 'he got nothing', 'she took potato and tomat']})
replacement = {
    "epples": "apples",
    "bakana": "banana",
    "tomat": "tomato"
}
print(df['Description'].replace(replacement, regex=True))

Output :

0          he wants some apples
1     she bought 2kgs of banana
2                he got nothing
3    she took potato and tomato

Answer 2

yes, in str.replace(something, toReplaceWith), you missed toReplaceWith so that it errors
