How can we select the first n rows of a Pandas DataFrame?

Suppose we’re working with this DataFrame df.

     x1   x2  x3  x4  y
0     7  143  22  23  1
1     1   23  22  29  0
2     3  133  24   0  1
3     1   39  27  23  0
4     0  137  40  23  1

If we only want the first 2 rows, then we can either slice by the actual index, or use -1.

df.iloc[:2,:]
df.iloc[:-1,:]

If we only want the last row (index of 4), once again, we can either slice by the actual index, or use -1.

df.iloc[4:,:]
df.iloc[-1:,:]


Revise the code and make it more robust with proper test case and check an error there before implementing into a production environment.
Now you can solve your code error in less than a minute.
