So I am trying to understand `partial`

:

```
import functools
def f(x,y) :
print x+y
g0 = functools.partial( f, 3 )
g0(1)
4 # Works as expected
```

In:

```
g1 = functools.partial( f, y=3 )
g1(1)
4 # Works as expected
```

In:

```
g2 = functools.partial( f, x=3 )
g2(1)
TypeError: f() got multiple values for keyword argument 'x'
```

The `TypeError`

disappears if I use `y`

as a keyword argument:

In:

```
g2( y=1 )
4
```

What causes the `TypeError`

?

From what i understand, 2.675 and numpy.float64(2.675) are both the same number. However, round(2.675, 2) gives 2.67, while round(np.float64(2.675), 2) gives 2.68. Why does this happen? import numpy ...
