Wie kann ich zwei Pandas DataFrames in Python horizontal (spaltenweise) kombinieren, ähnlich der Funktion „cbind' in R?

<code class="python">result = pd.concat([df_a, df_b], axis=1)</code>

<code class="python">import pandas as pd

dict_data = {'Treatment': ['C', 'C', 'C'], 'Biorep': ['A', 'A', 'A'], 'Techrep': [1, 1, 1], 'AAseq': ['ELVISLIVES', 'ELVISLIVES', 'ELVISLIVES'], 'mz':[500.0, 500.5, 501.0]}
df_a = pd.DataFrame(dict_data)

dict_data = {'Treatment1': ['C', 'C', 'C'], 'Biorep1': ['A', 'A', 'A'], 'Techrep1': [1, 1, 1], 'AAseq1': ['ELVISLIVES', 'ELVISLIVES', 'ELVISLIVES'], 'inte1':[1100.0, 1050.0, 1010.0]}
df_b = pd.DataFrame(dict_data)

result = pd.concat([df_a, df_b], axis=1)

print(result)</code>

1          C   1050  
2          C   1010  

<code class="python"># Using merge()
result = df_a.merge(df_b, left_index=True, right_index=True)

# Using join()
result = df_a.join(df_b)</code>
