I need your help on solving iterable and non-iterable values to find the minimum values.
Input:
D1={"Arcadia":{"Month": "January","Atmospheric pressure(hPa)":1013.25},"Xanadu":{"Month:"January","Atmospheric Pressure(hPa)":"No information"},"Atlantis":{"Month":"January","Atmospheric Pressure(hPa):2035.89}}
Output:
The city with the lowest pressure is Arcadia with the Atmospheric Pressure of 1013.25.
This is my code:
def lowest_pressure(dict1):
dict_pressure={}
exclude = "No information"
for city,data in dict1.items():
for value in str(data["Atmospheric Pressure(hPa)"]):
if value != exclude:
dict_pressure[city]=data["Atmospheric Pressure(hPa)"]
low_pressure=min(dict_pressure,key=dict_pressure.get)
print(f"The city that has the lowest Atmospheric Pressure is {low_pressure} with ${dict_pressure[low_pressure}hPa.")
lowest_pressure(D1)
If there is a dictionary comprehension I would like to know it too.
Thanks again SO community.

Having edited the dictionary content to what I think it should be, the resulting code should suffice:
D1 = {"Arcadia": {"Month": "January", "Atmospheric Pressure(hPa)": 1013.25},
"Xanadu": {"Month": "January", "Atmospheric Pressure(hPa)": "No information"},
"Atlantis": {"Month": "January", "Atmospheric Pressure(hPa)": 2035.89}
}
t = []
for k, v in D1.items():
try:
t.append((float(v['Atmospheric Pressure(hPa)']), k))
except ValueError:
pass
if t:
p, c = min(t)
print(f'The city with the lowest pressure is {c} with the Atmospheric Pressure of {p:.2f}')
else:
print('No valid pressure measurements available')
Output:
The city with the lowest pressure is Arcadia with the Atmospheric Pressure of 1013.25
