```{r}
bt <- reticulate::import_builtins()
bt$print("Hello world")
```
## Print statements should always be captured
In `jupyter_compat = FALSE`: we should only see the output of both expressions.
```{python}
print(1)
print(2)
```
In `jupyter_compat = TRUE`: we should only see the output of both expressions.
```{python, jupyter_compat = TRUE}
print(1)
print(2)
```
## Only outputs of last expressions are captured in jupyter compat
In `jupyter_compat = FALSE`: we should only see the output of both expressions.
```{python}
1 + 0
1 + 1
```
`jupyter_compat = TRUE`: we should only see the output of the last expression.
```{python, jupyter_compat = TRUE}
1 + 0
1 + 1
```
## One can disable outputs by using `;`
In `jupyter_compat = FALSE`: we should only see the print statement output
```{python}
print("hello");
1 + 0;
1 + 1;
```
`jupyter_compat = TRUE`: we should only see the print statement output
```{python, jupyter_compat = TRUE}
print("hello");
1 + 0;
1 + 1;
```
## `jupyter_compat` works with interleaved expressions
```{python, jupyter_compat=TRUE}
print('first_stdout')
'first_expression'
print('second_stdout')
'final_expression'
```
