split rows in pandas dataframe

Question

i stuck with the problem how to devide pandas dataframe by row,

i have similar dataframe with column where values separated by \\r\\n and they are in one cell,

Answer 1

This might not be the most efficient way to do it but I can confirm that it works with the sample df:

data = [['Green', 'Rectangle\r\nTriangle\r\nOctangle', 10], ['Blue', 'Rectangle\r\nTriangle', 15]]   
df = pd.DataFrame(data, columns = ['Color', 'Shape', 'Price'])
new_df = pd.DataFrame(columns = ['Color', 'Shape', 'Price'])

for index, row in df.iterrows():
    split = row['Shape'].split('\r\n')
    for shape in split:
        new_df = new_df.append(pd.DataFrame({'Color':[row['Color']], 'Shape':[shape], 'Price':[row['Price']]}))

new_df = new_df.reset_index(drop=True)
print(new_df)

Output:

   Color Price      Shape
0  Green    10  Rectangle
1  Green    10   Triangle
2  Green    10   Octangle
3   Blue    15  Rectangle
4   Blue    15   Triangle
