Python：如何以表格形式将数据写入电子表格

Question

I have a code that calculates a given function at different points, that is :

def f(x):
    return np.sin(x)
x=np.arange(-1,1,0.01)
print np.sin(x)

I want to store the values to an excel sheet using this format:

Is there a simple way to do it without using the pandas DataFrame since it this package is now working on my laptop

Answer 1

An easy way to do it is use the csv module to write to a csv file, which can then be read into excel.

An example would be:

import csv
import numpy as np

def f(val):
    return np.sin(val)

x = np.arange(-1, 1, 0.01)
y = f(x)

with open('outfile.csv', 'w') as fid:
    writer = csv.writer(fid)
    writer.writerow(['x'] + list(x))
    writer.writerow(['f(x)'] + list(y))

On the other hand, if you really want to write to excel, you can use packages that handle excel files. You can refer to http://www.python-excel.org/ for a list of relevant packages that are not pandas
