Here is a Python code to get a min value from column columns

import pandas as pd

def get_min_value(column):
  """Returns the minimum value in a column."""
  return min(column)

# Enter the dataframe
df = pd.DataFrame({'a': [1, 2, 3, 4, 5], 'b': [1, 2, 3, 4, 5]})

# Calling the function
print((get_min_value(df['a'])))

#Example Output
# 1

#Remember to inspect code for bugs.
