Remove all comma from starting and ending

For Example

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

Ans

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

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(',')

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:

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']]
