I tried below lines of code but not getting what I want.

for i in (df_merge.product_name):
print(i)

Answer 1

USING FOR LOOP Code:

for i in (df_merge.product_name):
    for s in i.split(','):
        print(s)

Output;

laptop
computer
printer
table
tablet
mobile
desk
chair
table

Answer 2

You can use .str.split(',') and then .explode() :

print(*df_merge["product_name"].str.split(",").explode(), sep="\n")

Prints:

laptop
computer
printer
table
tablet
mobile
desk
chair
table

If you want to explode whole dataframe:

df_merge["product_name"] = df_merge["product_name"].str.split(",")
df_merge = df_merge.explode("product_name")
print(df_merge)

Prints:

  product_name  price
0       laptop   1200
0     computer   1200
1      printer    150
1        table    150
2       tablet    300
2       mobile    300
3         desk    450
4        chair    200
4        table    200
