You canuse pandas to solve this problem as given below,

df = pd.DataFrame({'column1': ["Movie", "actor", "xyz"], 'column2': ["Thor", "xyz", "xyz"],'column3': ["Marvel", "xyz", "xyz"]})

df = pd.read_csv("check.csv")

idx = 1
column_x = ["newc1", "newc2", "newc3"]  
df.insert(loc=idx, column='columnx', value=column_x)
df
   column1 columnx column2 column3
0   Movie   newc1    Thor  Marvel
1   actor   newc2     xyz     xyz
2     xyz   newc3     xyz     xyz
