How can I replace the "." in a float with "

Python code (can't change this):

import numpy as np
        
for VALUES in np.arange(0.1, 0.3, 0.1):
    print("Value: %s" % (VALUES))

Output:

Value: 0.1
Value: 0.2

Desired output:

Value: 0_1
Value: 0_2

I am a beginner when it comes to python, and I'm struggling with this simple task. Is this possible with the replace() method? Do I need to create a new function that makes the replacement?

It's hard to tell given the limited information provided.

But if you want to make the replacement just for the code shown here you can do this:

import numpy as np
        
for VALUES in np.arange(0.1, 0.3, 0.1):
    print("Value: %s" % (str(VALUES).replace(".", "_")))

But I am not sure what you mean when you say "can't change this".

Hope this gives a hint at least.

It's very simple to do, you need to convert the float to a string.

float_value = 0.1
string_value = str(float_value)

Then you can use the replace() function

string_value = string_value.replace(".","_")
