## Context Managers { #context-managers }

### What are "Context Managers" { #what-are-context-managers }

"Context Managers" are any of those Python objects that you can use in a `with` statement.

For example, [you can use `with` to read a file](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

```Python
with open("./somefile.txt") as f:

  // Initialize a input_tensor vector with `nullptr` values.
  std::vector<const Tensor*> input_tensors_vector(num_inputs, nullptr);
  // A vector to keep track of newly created `tf::Tensor` objects.
  std::vector<Tensor> all_input_tensors;
  // Update the vector with information from `input_tensors` if provided.
  if (input_tensors != nullptr) {
    // Note that we take the address of the elements in `all_input_tensors`

      assertTrue(tlsVersion == TlsVersion.TLS_1_2 || tlsVersion == TlsVersion.TLS_1_3)
      assertEquals(
        "CN=localhost",
        (response.handshake!!.peerCertificates.first() as X509Certificate).subjectDN.name,
      )
    }
  }

  @Test
  fun testCertificatePinningFailure() {
    enableTls()

    val certificatePinner =
      CertificatePinner
        .Builder()
