# Examples

Here are some examples of how to use the E2B Code Interpreter package. If you are missing something, please let us know.

## Minimal example with the sharing context

The following example demonstrates how to create a shared context between multiple code executions. This is useful when you want to share variables between different code cells.

<CodeGroup isRunnable={false}>
```js
import { CodeInterpreter } from '@e2b/code-interpreter'

const sandbox = await CodeInterpreter.create()
await sandbox.notebook.execCell('x = 1')

const execution = await sandbox.notebook.execCell('x+=1; x')
console.log(execution.text)  // outputs 2

await sandbox.close()
```
```python
from e2b_code_interpreter import CodeInterpreter

with CodeInterpreter() as sandbox:
    sandbox.notebook.exec_cell("x = 1")

    execution = sandbox.notebook.exec_cell("x+=1; x")
    print(execution.text)  # outputs 2

```
</CodeGroup>

## Get charts and any display-able data

<CodeGroup isRunnable={false}>
```js
import { CodeInterpreter } from '@e2b/code-interpreter'

const sandbox = await CodeInterpreter.create()

const code = `
import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 20, 100)
y = np.sin(x)

plt.plot(x, y)
plt.show()
`;

// you can install dependencies in "jupyter notebook style"
await sandbox.notebook.execCell("!pip install matplotlib")

const execution = await sandbox.notebook.execCell(code)

// this contains the image data, you can e.g. save it to file or send to frontend
execution.results[0].png

await sandbox.close()
```
```python
import base64
import io

from matplotlib import image as mpimg, pyplot as plt

from e2b_code_interpreter import CodeInterpreter

code = """
import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 20, 100)
y = np.sin(x)

plt.plot(x, y)
plt.show()
"""

with CodeInterpreter() as sandbox:
    # you can install dependencies in "jupyter notebook style"
    sandbox.notebook.exec_cell("!pip install matplotlib")

    # plot random graph
    execution = sandbox.notebook.exec_cell(code)

# there's your image
image = execution.results[0].png

# example how to show the image / prove it works
i = base64.b64decode(image)
i = io.BytesIO(i)
i = mpimg.imread(i, format='PNG')

plt.imshow(i, interpolation='nearest')
plt.show()
```
</CodeGroup>

## Streaming code output

<CodeGroup isRunnable={false}>
```js
import { CodeInterpreter } from "@e2b/code-interpreter";

code = `
import time
import pandas as pd

print("hello")
time.sleep(3)
data = pd.DataFrame(data=[[1, 2], [3, 4]], columns=["A", "B"])
display(data.head(10))
time.sleep(3)
print("world")
`

const sandbox = await CodeInterpreter.create()

await sandbox.notebook.execCell(code, {
  onStdout: (out) => console.log(out),
  onStderr: (outErr) => console.error(outErr),
  onResult: (result) => console.log(result.text)
})
````
```python
from e2b_code_interpreter import CodeInterpreter

code = """
import time
import pandas as pd

print("hello")
time.sleep(3)
data = pd.DataFrame(data=[[1, 2], [3, 4]], columns=["A", "B"])
display(data.head(10))
time.sleep(3)
print("world")
"""
with CodeInterpreter() as sandbox:
    sandbox.notebook.exec_cell(code, on_stdout=print, on_stderr=print, on_result=(lambda result: print(result.text)))
```
</ CodeGroup>
