I am trying to make a pandas dataframe using 2 paramters as columns. But it makes a dataframe transpose of what I need. 
I have `a` and `b` as column parameters as follows:

```
a=[1,2,3,4,5]
b=[11,22,33,44,55]

pd.DataFrame([a,b])

```

This gives the following dataframe:

```

    0   1   2   3   4 
0   1   2   3   4   5
1   11  22  33  44  55

```

However, I want the dataframe as:

```
    0   1 
0   1   11
1   2   22
2   3   33
3   4   44
4   5   55

```
