Son's homework

[Sinky100]

Hi,

My son is is having issues with the below homework.

For a temporary wifi system at an event:
- Enter number of Access Points (AP):
- Enter the signal strength (0-100) for each access point.
- Convert signal strength input to Strong (S), Medium (M), Poor (P)
- Output a string with the conversions (e.g, for 5 APs, a possible output would show as "SMMPS".

He wrote the below code, but it is only outputting the conversion of the last signal entered. This is frustrating for him as his last homework for a program to calculate a students grade based on marks had the same issue. For that homework his teacher mentioned a possible issue with his indentation?!?!

Any help would be appreciated. I am newer than my son at this!

Thanks, Iain

signal_array = []  

locations_array = []  

signal_d = [] 

#inputs  
locations = int(input("How many locations at this site?"))  

for i in range(locations):
    locations_array.append (input("Enter location name: "))  
    signal = float(input("Enter signal strength: "))  
#validation  
    while signal < 0 or signal >100:  
        print("Enter a valid signal strength (0-100)")  
        signal = float(input("Enter signal strength: "))  
    signal_array.append(signal)  

#conversion  
for i in (signal_array): 
    if signal > 80:
        grade = 'S' 
        
    elif signal < 30: 
        grade = 'P' 
    
    else: 
        grade = 'M' 

signal_d.append(grade) 

#output
for i in (signal_d): 
    print()           
    print (i, end="")

Output was as follows:

How many locations at this site?
5
Enter location name:
1
Enter signal strength:
45
Enter location name:
2
Enter signal strength:
45
Enter location name:
3
Enter signal strength:
78
Enter location name:
4
Enter signal strength:
99
Enter location name:
5
Enter signal strength:
87

Line 30 should be indented in order to belong to the 'for' loop just above it. The grade needs to be appended to the list for every signal and not only the last one.
