Question

1. We have sever ral Fahrenheit degrees in a fi e 'Fdeg.dat and want to to read all of them into a list and convert the numbers to Celsius degrees. Thereafter, we want to write out a file named degrees.dat with two columns, the left with the Fahrenheit degrees and the right with the Celsius degrees. Fahrenheit degree can be converted to Celsius by: C (5.0/9) * (F-32) An example on the input file format looks like: Temperature data Fahrenheit degrees: 67.2 Fahrenheit degrees: 66.0 Fahrenheit degrees: 78.9 Fahrenheit degrees: 102.1 Fahrenheit degrees: 32.0 Fahrenheit degrees: 87.8

Answer 1

Code with indentation:

7 import csv 8 f open(. Fdeg.dat', 'r') #open file in read mode 9 Fdeg-[] 10 for line in f.readlines (): 12 ts]ine. split(":") #splits line into two strings by delimiter : 13 Fdeg.append(float(t[1])) #appends temperature to list 14 f.close() 15 16 Cdeg=[] #list stores celcius temp 17 18 for i in range(len(Fdeg)): 19 cel-((5.0)/9)*((Fdeg[1])-32) #calculates celcius 20 Cdeg.append(round(cel,2)) #appends to list 21 2221p (Fdeg, Cdeg) #zips two lists 23 with open( 'degrees. dat','w') as f: #open file in write mode 24 writer csv.writer(f,delimiter.it') #writes in file with delimiter 25 writer.writerows (zip(Fdeg,Cdeg)) #write row by row in file 26 space

Output:

Fdeg - Notepad File Edit Format View Help Fahr enheit degrees:67.2 Fahr enheit degrees:66.0 Fahr enheit degrees:78.9 Fahr enheit degr ees:102.1 Fahr enheit degrees:32.0 Fahrenheit degrees:87.8

Result is stored in degrees.dat file

While executing values of Fahrenheit and celsius in lists

Cdeg List (6 elements) Index Type Size e float 1 67.2 1 float 1 66.8 Index Type Size 0 float 1 19.56 1 float 18.89 2 float 1 26.86 3 float 1 38.94 4 float 1 0.0 float 1 78.9 3 float 1 102.1 4 float 1 32.0 5 float 1 31. 5 float 1 87.8

Code:

import csv
f = open('Fdeg.dat', 'r') #open file in read mode
Fdeg=[]
for line in f.readlines():
t=[]
t=line.split(":") #splits line into two strings by delimiter :
Fdeg.append(float(t[1])) #appends temperature to list
f.close()

Cdeg=[] #list stores celcius temp

for i in range(len(Fdeg)):
cel=((5.0)/9)*((Fdeg[i])-32) #calculates celcius
Cdeg.append(round(cel,2)) #appends to list

zip(Fdeg,Cdeg) #zips two lists
with open('degrees.dat','w') as f: #open file in write mode
writer=csv.writer(f,delimiter='\t') #writes in file with delimiter space
writer.writerows(zip(Fdeg,Cdeg)) #write row by row in file
