Why is "weights" in the function header and loop

[paulgureghian]

# Define predict_with_network()
def predict_with_network(input_data_row, weights):

# Calculate node 0 value
node_0_input = (input_data_row * weights['node_0']).sum()
node_0_output = relu(node_0_input)

# Calculate node 1 value
node_1_input = (input_data_row * weights['node_1']).sum()
node_1_output = relu(node_1_input)

# Put node values into array: hidden_layer_outputs
hidden_layer_outputs = np.array([node_0_output, node_1_output])

# Calculate model output
input_to_final_layer = (hidden_layer_outputs * weights['output']).sum()
model_output = relu(input_to_final_layer)

# Return model output
return(model_output)


# Create empty list to store prediction results
results = []
for input_data_row in input_data:
# Append prediction to results
results.append(predict_with_network(input_data_row, weights))

# Print results
print(results)

why is the "weights" array set as a param in the function header and in the function call in the loop body, while in the other script its not in the function header yet it is still accessible in the function body ?
