How do you run behave (with python code) steps implementation with gherkin scenarios data input? - python-behave

Question

I start python and TDD, I would like to know how to run behave steps with python and scenarios table for the two scenarios below:
The program ask a user to enter data (humididity level and temperature) and it prints those data.
For the first scenario, user fill out data and the program prints those data (normal case). I just want to check if there is data input
For the second scenario, if user fill out "text" the program return a syntax error.I would like to check the data type in #then steps
The problem is that when I run steps with behave command it asks me to enter data but I want the program uses data table in gherkin scenarios. Can you help please?
gherkin scenario below:
Feature: As a user I want fill out humidex data to visualize it
Scenario: user fill out humidex data correctly
Given a user
When user fill out humidexdata
|humidity|temperature|
|50% |28C° |
Then user visualize
|humidity|temperature|
|50% |28C° |
Scenario: user fill out humidex data with text
Given a user
When user fill out humidexdata
|humidity |temperature|
|lorem ipsum|lorem ipsum|
Then user visualize a syntax error "data syntax is wrong retry"
step implementations with behave:
from behave import *
from fillouthumidexdata import *
#given(u'a user')
def step_impl(context):
context.user = User()
#when(u'user fill out humidexdata')
def step_impl(context):
context.user.fillout_humidexData()
#then(u'user visualize')
def step_impl(context):
context.user.visualize_humidexData()
python code:
class User():
def __init__(self):
self.humidity = []
self.temperature =[]
def fillout_humidexData(self):
print("Enter humidity level (%)")
input(self.humidity)
print("Enter temperature (C°)")
input(self.temperature)
def visualize_humidexData(self):
print(self.humidity)
print(self.temperature)

I am not sure why you need actually separate User class as all of that can be done in simple steps, but following this approach I would change first a bit the User class at least to:
class User():
def __init__(self):
self.humidity = 0
self.temperature = 0
def fillout_humidexData(self, humidity, temperature):
self.humidity = humidity
self.temperature = temperature
def visualize_humidexData(self):
print(f'humidity: {self.humidity}')
print(f'temperature: {self.temperature}')
And then use the following steps:
from behave import step, given, when, then
from fillouthumidexdata import *
#given(u'a user')
def step_impl(context):
context.user = User()
#when(u'user fill out humidexdata')
def step_impl(context):
humidity, temperature = context.table.rows[0]
context.user.fillout_humidexData(humidity, temperature)
#then(u'user visualize')
def step_impl(context):
context.user.visualize_humidexData()
rows[0] should give you values from first row in your setup table(2 values from 2 columns).
I think this should work, but I am not sure if this is what you want.
