# Callable.start\_loop\_instructions()

Returns start\_loop instructions of the function/modifier.

`start_loop_instructions() →` [`Instructions`](/glider-ide/api/instructions.md)

The functions will return start\_loop instructions for all types of loops e.g. while/for.

start\_loop instruction is not a "real" instruction but rather an abstract one representing the start of the loop.

## Example

```python
from glider import *
def query():
  functions = Functions().exec(100)

  loop_instructions = []
  for function in functions:
    for instruction in function.start_loop_instructions().exec():
      # Return the starting loop instructions for each function
      loop_instructions.append(instruction)

  return loop_instructions
```
