date_range = pd.timedelta_range(0, periods=49, freq='H')
print("Hourly range of perods 49:")
print(date_range)
``````

Sample Output:

```Hourly range of perods 49:

Merging two dicts in Python 3.5+ with a single expression

Example:

```# How to merge two dictionaries
# in Python 3.5+

x = {'p': 1, 'q': 3}
y = {'q': 5, 'r': 8}

z = {**x, **y}

z
{'r': 4, 'p': 1, 'q': 3}

z = dict(x, **y)
print(z)
```

Output:

```{'p': 1, 'q': 5, 'r': 8}
```
