iPython lprun不打印输出

Question

I don't know what's going on here, so thought I would ask you guys.

I just installed iPython 3.1 on Mac OSX 10.10.2

In iPython I tried my function with no results, but here is an example:

In [21]: def rn():
   ....:     for ix in range(0,100): print ix
   ....:

In [22]: %lprun rn()
0
1
2
3
4
....
98
99
Timer unit: 1e-06 s

In this type of situation I'm expecting a normal cProfile type output, showing the lines that ran and how long each one took. What am I doing wrong?!

Thanks!

Answer 1

Use the -f flag to get line by line output:

%lprun -f rn  rn()

Output:

In [13]: %lprun -f rn  rn()
0
1
2
3
4
5
...
94
95
96
97
98
99
