Why running Python code in Rstudio gives redundant text?

Question

I am running the following python code in R-notebook:

```{r}
library(reticulate)
```

```{python}
import matplotlib
import numpy as np
import matplotlib.pyplot as plt

import matplotlib.pyplot as plt
import numpy as np

t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2*np.pi*t)
plt.plot(t, s)

plt.xlabel('time (s)')
plt.ylabel('voltage (mV)')
plt.title('About as simple as it gets, folks')
plt.grid(True)
plt.savefig("test.png")
plt.show()

```

It's strange because besides a plot, there is a text result.

Could you please explain the reason for this phenomena?

Here is @Onyambu comment. I post it here to remove my question from unanswered list.

Well this is a behaviour of matplotlib. Even in python itself, unless you save the output to a given variable, there will be text printed on your console
