Solutions: Use np.repeat: Version 1: Try using np.repeat: newdf = pd.DataFrame(np.repeat(df.values, 3, axis=0)) newdf.columns = df.columns print(newdf) The above code will output: Person ID ZipCode Gender 0 12345 882 38182 Female 1 12345 882 38182 Female 2 12345 882 38182 Female 3 32917 271 88172 Male 4 32917 271 88172 Male 5 32917 271 88172 … Read more

a = [‘1’, ‘1’, ‘1’, ‘1’, ‘1’, ‘1’, ‘2’, ‘2’, ‘2’, ‘2’, ‘7’, ‘7’, ‘7’, ’10’, ’10’] print a.count(“1”) It’s probably optimized heavily at the C level. Edit: I randomly generated a large list. In [8]: len(a) Out[8]: 6339347 In [9]: %timeit a.count(“1”) 10 loops, best of 3: 86.4 ms per loop Edit edit: This … Read more
