``````import pandas as pd
my_lists = [['col1', 'col2'], [2, 4], [1, 3]]
# sets the headers as list
print("Original list of lists:")
print(my_lists)
df = pd.DataFrame(my_lists, columns = headers)
print("New DataFrame")

## Python: Tips of the Day

Inserting if statements using conditional list comprehensions:

```x = [1, 2, 3, 4, 5, 6]
result = []
for idx in range(len(x)):
if x[idx] % 2 == 0:
result.append(x[idx] * 2)
else:
result.append(x[idx])
result
```

Output:

```[1, 4, 3, 8, 5, 12]
```
`[(element * 2 if element % 2 == 0 else element) for element in x]`

Output:

```[1, 4, 3, 8, 5, 12]
```
`[element * 2 for element in x if element % 2 == 0]`

Output:

```[4, 8, 12]
```
