Im new in programming and I want to fill just the first column of a matrix with diferent random float within a certain range (low and high limits), but when I run my code it fills all the rows in the first column with the same value. Please help me! :)

import numpy as np import random res=np.zeros([5,2])#empty matrix first_col_res=res[:,0] #the first column of matrix res seen=set() def rand_teta(low, high,k):#k refers to the total random numbers: j=0 while j <=k: x=random.uniform(low,high) j=j+1 while x in seen: x=random.uniform(low,high) seen.add(x) first_col_res.fill(x) return res #out put example rand_teta(1,2,3)

```
Output:
Out[88]:
array([[1.72762661, 0. ],
[1.72762661, 0. ],
[1.72762661, 0. ],
[1.72762661, 0. ],
[1.72762661, 0. ]])
```
