Pandas Brain Teasers

# Try it yourself
Try executing the code below to see the result.

import pandas as pd

df = pd.DataFrame([[1, 2], [3, 4]], columns=['x', 'y'])
print(df.to_csv())

# Explanation
What’s going on in the unnamed column with 0 and 1 values?

The `pandas.DataFrame` documentation has this to say:

>"Data structure also contains labeled axes (rows and columns). Arithmetic operations
align on both row and column labels. Can be thought of as a `dict`-like container for Series objects. The primary pandas data structure."

The labeled axis for rows is called the **index**.
When we convert a `pandas.DataFrame` to another format (for example, CSV or SQL), it
will add the index by default.

We can use `index=False` to omit the index.
```py
In [1]: print(df.to_csv(index=False))
x,y
1,2
3,4
```

# Solution

import pandas as pd

df = pd.DataFrame([[1, 2], [3, 4]], columns=['x', 'y'])
print(df.to_csv(index=False))
