Panda Lighter-Life Guard ‘df = pd.read_csv (data, index_col = 0)’ What does index_col = 0 mean?
2. pd.read_csv(index_col=0)
import pandas as pd
df = pd.read_csv('test.csv', index_col=0)
print(df)
print(df.index)
print(df.columns)
print(df.head)
-
pd.read_csv(‘data_file.csv’) : Read the ‘test.csv’ file. Here the PD created a DataFrame object. This is because the index_col parameters specify 0_NAME and 1_INXEX to be used in the CSV file to create a DataFrame object after reading the file.
-
df.index: Check the index of DF, a DataFrame object. The index represents the row of the data frame and basically starts with 0.
print(df.index)
Dict-Key 0
Zero 1
One 2
Two 3
Three 3
Four 4
Name: index, dtype: int64
- df.columns: Print the column name of the DataFrame object. This property allows you to check what kind of data you have in each column of the data frame.
print(df.columns)
Index(['index'], dtype='object')
- df.head: A function, and the function is parenthesized. The object runs the function.
print(df.head)
Print index, columns, df.head

Examining 'pd.read_csv':
'pd' suggests 'pandas', a well-known data manipulation library in Python.
The method 'read_csv' is used to read data from a CSV file into a DataFrame.
interpreting the code:
'type'(pd.read_csv) determines the 'type' of the object pd.read_csv, which is a tuple.
