Answer 1

python strip function lets you specify a character to strip from the start and end, so this should work:

df = df['name'].apply(lambda x: x.strip(','))

Or even more simply using the str handle to access python string functions:

df = df['name'].str.strip(',')

And also with a list comprehension (thanks to @Celius Stingher for this suggestion)

df['name'] = [x.strip() for x in df['name']]

example with data:

import pandas as pd

df = pd.DataFrame(
{
    'name': [',,par, ind, gop, abc', ',raj,', 'marl, govin', 'rajjs', 'sun,,,']
})
df = df['name'].str.strip(',')
print(df)

result:

id	name
0	par, ind, gop, abc
1	raj
2	marl, govin
3	rajjs
4	sun

You can perform it faster and more efficient way using list comprehensions, avoiding the need for apply or lambdas:

df['name'] = [x.strip() for x in df['name']]
