dedylja [7]

Answer:

celciusFile=open("celcius.dat","r")

fahrenheitFile=open("fahrenheit.dat","w")

# Iterate over each line in the file

for line in celciusFile.readlines():

# Calculate the fahrenheit

fahrenheit = 9.0 / 5.0 * float(line) + 32

#write the Fahrenheit values to the Fahrenheit file

fahrenheitFile.write("%.1f\n" % fahrenheit)

# Release used resources

celciusFile.close()

fahrenheitFile.close()

Explanation:

celciusFile=open("celcius.dat","r")

fahrenheitFile=open("fahrenheit.dat","w")

open the Celsius file in the read mode and assign it to a variable.

open the Fahrenheit file in the write mode and assign it to a variable.

read mode means you can only use/read the content in the file but cannot alter it.

write mode means you can write new data to the file.

# Iterate over each line in the file

for line in celciusFile.readlines():

The values contained in the Celsius file are collected.

# Calculate the fahrenheit

fahrenheit = 9.0 / 5.0 * float(line) + 32

The values are then converted to Fahrenheit.

#write the Fahrenheit values to the Fahrenheit file

fahrenheitFile.write("%.1f\n" % fahrenheit)

The Fahrenheit values are written to the Fahrenheit file

%.1f is used to specify the number of digits after decimal. and \n adds a new line.

# Release used resources

celciusFile.close()

fahrenheitFile.close()

All files are closed
