hii experts i have a text file(input.txt) that contain 5 columns data as given below:
2 3 4 5 6
3 4 5 6 7
2 3 4 5 6
6 7 8 9 0
3 3 3 3 3
i just want to read single column at each iteration and want to add 5 on it and want np.savetxt to save each iteration output of the loop in different column of a text file
i wrote the script
import numpy as np
import random
inpdata=np.loadtxt("input.txt")
for x in np.arange(0,4,1):
data=inpdata[:,x]
sum=data+5
np.savetxt('tx_'+str(x),data)
while doing this output are saved in different files but i need output to be saved in single file as firstcolumn,second column, third column.... i need output like as below
7 8 9 10 11
8 9 10 11 12
7 8 9 10 11
11 12 13 14 5
8 8 8 8 8
i hope some expert will help me .Thanks in advance.
Since you just perform some manipulation on an array. You could equivalently do the following:
In this specific example, you could just add a scalar to you array like the following:
import numpy as np
data=np.loadtxt("test.txt")
data += 5
np.savetxt('output.txt', data)
And if you insist to do it column-wise:
import numpy as np
data=np.loadtxt("test.txt")
for i in range(data.shape[1]):
data[:, i] += 5
np.savetxt('output.txt', data)
