[FIXED] I want to 2 decimal points result for predicts on Python

Issue

My outputs have too much decimal points. But I want to 2 points float results. Can you help me?

EX: 42.44468745 -> 42.44

y_pred=ml.predict(x_test)
print(y_pred)

Output:

[42.44468745 18.38280575  7.75539511 19.05326276 11.87002186 26.89180941
 18.97589775 22.01291508  9.08079557  6.72623692 21.81657224 22.51415263
 24.46456776 13.75392096 21.57583275 25.73401908 30.95880457 11.38970094
  7.28188274 21.98202474 17.24708345 38.7390475  12.68345506 11.2247757
  5.32814356 10.41623796  7.30681434]

Solution

Since you didn't post all of your code, I can only give you a general answer.

There are several ways to get two decimals.

For example:

num = 1.223362719

print('{:.2f}'.format(num))

print('%.2f' % num)

print(round(num, 2))

print(f"{num:.2f}")

You will get 1.22 as the result of any of these.

Thanks for commenting, and I have updated to deal with your problem.

Using numpy could help you when your data OP is using an ndarray.

You can use data= np.around(a, n) # a is the data that needs to be decimal processed, and n is the reserved number.

Example:

    import numpy as np
    data= np.around(1.223362719, 2) 

You will also get 1.22 as the result.
