[Python] Fix: ValueError: All arrays must be of the same length

>>> import pandas as pd
>>> df = pd.DataFrame({
...     'A': [1,2,3],
...     'B': [4,5,6],
...     'C': [7,8,9,10]
... })

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/pandas/core/frame.py", line 709, in __init__
    mgr = dict_to_mgr(data, index, columns, dtype=dtype, copy=copy, typ=manager)

raise ValueError("All arrays must be of the same length")
ValueError: All arrays must be of the same length

You will get an ValueError when working with Pandas DataFrame in Python if you create columns with different lengths.

All columns in a DataFrame must have the same length in Pandas.

As you can see in the above example, column C has a length of 4 whereas other columns have a length of 3.


We make sure that the length of columns in the data frame are the same.

df = pd.DataFrame({
    'A': [1,2,3],
    'B': [4,5,6],
    'C': [7,8,9]
ValueError- All arrays must be of the same length
