Into This:
I already have the first table in a data frame in python as df3. How do I get what the output I want using pandas preferably in python. Let me know if you need the raw data I will send it to you

Assuming this input:
ID Invoice DO other_cols
0 A a 1,2,3 xxx
1 B b 4,5 xxx
2 C c 6 xxx
You could use assign str.split to transform your string into list, and explode to generate one row per item in the list:
(df.assign(DO=df['DO'].str.split(','))
.explode('DO')
)
output:
ID Invoice DO other_cols
0 A a 1 xxx
0 A a 2 xxx
0 A a 3 xxx
1 B b 4 xxx
1 B b 5 xxx
2 C c 6 xxx
