Question

In python, write the contents of the x and y lists to a file called xy2.dat with one value from x and y on each line, separated by a comma.

x = [-1.0, -0.9, -0.8, -0.7, -0.6, -0.5, -0.4,
-0.30000000000000004, -0.19999999999999996, -0.09999999999999998,
0.0, 0.10000000000000009, 0.19999999999999996, 0.30000000000000004,
0.3999999999999999, 0.5, 0.6000000000000001, 0.7, 0.8,
0.8999999999999999, 1.0]

y = [1.0, 0.78, 0.67, 0.51, 0.27, 0.0, 0.14, 0.19, -0.14, 0.03,
0.03, -0.09, -0.03, -0.12, 0.14, 0.36, 0.57, 0.63, 0.61, 0.59, 1.01]

Answer 1

#solution for the above problem

Code:

#opening or creating file named xy2.dat if file does not exits it create

a=open("xy2.dat",mode="w")

#intial data of x and y

x = [-1.0, -0.9, -0.8, -0.7, -0.6, -0.5, -0.4,
-0.30000000000000004, -0.19999999999999996, -0.09999999999999998,
0.0, 0.10000000000000009, 0.19999999999999996, 0.30000000000000004,
0.3999999999999999, 0.5, 0.6000000000000001, 0.7, 0.8,
0.8999999999999999, 1.0]

y = [1.0, 0.78, 0.67, 0.51, 0.27, 0.0, 0.14, 0.19, -0.14, 0.03,
0.03, -0.09, -0.03, -0.12, 0.14, 0.36, 0.57, 0.63, 0.61, 0.59, 1.01]

#iterating the data to write to the file

for i in range(len(x)):
  
#writing the value of x
a.write(str(x[i]))

#with seperated by comma
a.write(',')

#wiritng the value of y
a.write(str(y[i]))

#entering into the newline
a.write('\n')

#closing the file
a.close()

#reopen the file to show output
b=open("xy2.dat",mode="r")

#finally written information in the file named xy2
print(b.read())

#Screenshots

#output
