how to normalize when max = min code example

Example: Min Max Normalization

# copy the data
df_min_max_scaled = df.copy()
  
# apply normalization techniques by Column 1
column = 'Column 1'
df_min_max_scaled[column] = (df_min_max_scaled[column] - df_min_max_scaled[column].min()) / (df_min_max_scaled[column].max() - df_min_max_scaled[column].min())    
  
# view normalized data
display(df_min_max_scaled)
