Beautification of the print output of the console

Question

I have an output in the Console. Unfortunately the texts are of different length and therefore looks very shifted. Is there an option that writes the texts below each other, no matter how many characters are in front of them, so that the output looks the way I want it to look?

I would not like to use another library for this.

print(65 * '_')
print('algorithm\t\t\tsil\t\tdbs')

results =  ['Agglomerative Clustering', 0.8665, 0.4200]
formatter_result = ("{:9s}\t\t{:.4f}\t{:.4f}")
print(formatter_result.format(*results))
    
results = ['k-Means', 0.9865, 0.1200]
formatter_result = ("{:9s}\t\t{:.4f}\t{:.4f}")
print(formatter_result.format(*results))

print(65 * '_')

What I have

_________________________________________________________________
algorithm           sil     dbs
Agglomerative Clustering        0.8665  0.4200
k-Means         0.9865  0.1200

What I want

I looked at Printing Lists as Tabular Data and tried it, but dosen't work for me

print(65 * '_')

heading = ['algorithm', 'sil', 'dbs']
result1 =  ['Agglomerative Clustering', 0.8665, 0.4200]
result2 = ['k-Means', 0.9865, 0.1200]
ab = np.array([heading, result1, result2])
for row in ab:
    print("{: >20} {: >20} {: >20}".format(*row))
    



print(65 * '_')

             k-Means               0.9865                 0.12

hi so you have to remove some \t cause they create tabs and you can remove them one by one to find one that you prefer

print('for example, this is a tab \t\t\t there is going to be space between them')

print('for example, there is no tab here and it is going to be next to each other')

You could use {:<20}, this means 20 spaces with left alignment. There is also {:^20} - center alignment and {:>20}- right alignment.

To combine it with float notation e.g. .4f just add to it: {:<20.4f}

Try this:

print(65 * "_")
formatter_result = "{:<35} {:<20} {:<20}"
formatter_result_f = "{:<35} {:<20.4f} {:<20.4f}"
print(formatter_result.format(*["algorithm", "sil", "dbs"]))
results = ["Agglomerative Clustering", 0.8665, 0.4200]
print(formatter_result_f.format(*results))
results = ["k-Means", 0.9865, 0.1200]
print(formatter_result_f.format(*results))
print(65 * "_")

Result:
