In Python, one of the most common tasks is to use the output of one function as input for another function. This can typically be done by returning a value from the first function, then passing the returned value as an argument to the second function. In this tutorial, we will walk through the process of getting a value from one function and using it in another function.

### Step 1: Define the First Function

First, we need to create a function that generates a value that we want to use in another function. This can be done using the `def`

keyword followed by the function name and a set of parentheses. In the example below, we define a simple function that adds two numbers and returns the result.

def add_numbers(a, b): return a + b |

### Step 2: Define the Second Function

Next, we define the second function that takes the result from the first function and does something with it. For this example, we create a function that multiplies the result of the previous function by a given number.

def multiply_result(result, multiplier): return result * multiplier |

### Step 3: Call the First Function and Store the Result

Now, we can call our first function and store the returned value in a variable. This value can then be passed as an argument to our second function. In this example, we call the `add_numbers`

function, passing `3`

and `4`

as arguments, and store the result in a variable called `sum_result`

.

sum_result = add_numbers(3, 4) |

### Step 4: Call the Second Function with the Stored Result

Finally, we can call our second function and pass the result from the first function as an argument. In our example, we call the `multiply_result`

function, passing `sum_result`

and our desired multiplier (`2`

, in this case) as arguments. The output of this final call will be the product of the added numbers and the multiplier.

final_result = multiply_result(sum_result, 2) print(final_result) |

## Output:

14

## Full Code:

1 2 3 4 5 6 7 8 9 10 |
def add_numbers(a, b): return a + b def multiply_result(result, multiplier): return result * multiplier sum_result = add_numbers(3, 4) final_result = multiply_result(sum_result, 2) print(final_result) |

## Conclusion

Getting a value from one function and using it in another function is a straightforward process in Python. By following the steps outlined in this tutorial, you can effectively utilize function outputs in other functions to create more complex and efficient code.
