numpy.savetxt()

[mesh01]

Hi,

this code works fine:

import numpy as np
  
data = np.array([3,2,55,4])

for i in range(4):
    data[i] = data[i]+3

    print("text before", data[i], "text after")

Output:

Output:
~/pro$ python max.py
('text before', 6, 'text after')
('text before', 5, 'text after')
('text before', 58, 'text after')
('text before', 7, 'text after')

But I can't save in the file output.txt.
I tried with numpy.savetxt()

np.savetxt("output.txt", ???, fmt='%i', delimiter=",")

What should i add in this code?

Thanks

m.

Can do it like this,since you take values out of the numpy arrary.

import numpy as np

data = np.array([3,2,55,4])
with open('output.txt', 'w') as f_out:
    for i in range(4):
        data[i] = data[i]+3
        print(f"text before, {data[i]}, text after")
        f_out.write(f"text before, {data[i]}, text after\n")

Output:
text before, 6, text after
text before, 5, text after
text before, 58, text after
text before, 7, text after

text before, 5, text after
text before, 58, text after
text before, 7, text after

Now it works fine.

Thank you,
