# Array1 Example
# Read an array from a file, then
# compute the sum of the array elements.

# Initialize array.  This must be done
#outside of the code block
# File.open, otherwise values goes away when
# exiting the code block.

values = [ ]

# Open input file.
f = open("values1.txt", "r")

# Read and process file.
line = f.readline( )
while line:
    value = float(line.strip( ))
    values.append(value)
    line = f.readline( )
    
# Close input file.
f.close( )

# Loop over the array elements to compute the sum.
# The variable sum contains the partial sum after adding
# each value.
sum = 0.0
for x in values:
    sum += x

# Print the sum with two digits after the decimal point.
print(f"Sum = {sum}")
