Python Pandas - How to create a RangeIndex

To create a RangeIndex, use the pandas.RangeIndex() method in Pandas. At first, import the required libraries −

import pandas as pd

RangeIndex is a memory-saving special case of Int64Index limited to representing monotonic ranges. Using RangeIndex may in some instances improve computing speed.

Create a range index with start, stop and step. The name is the name to be stored in the index −

index = pd.RangeIndex(start=10, stop=30, step=2, name="data")

Display the start parameter value −

print("\nRangeIndex start value...\n",index.start)

Display the stop parameter value −

print("\nRangeIndex stop value...\n",index.stop)

Display the step parameter value −

print("\nRangeIndex step value...\n",index.step)

Example

Following is the code −

import pandas as pd

# Create a range index with start, stop and step
# The name is the name to be stored in the index.
index = pd.RangeIndex(start=10, stop=30, step=2, name="data")

# Display the RangeIndex
print("RangeIndex...\n",index)

# Display the start parameter value
print("\nRangeIndex start value...\n",index.start)

# Display the stop parameter value
print("\nRangeIndex stop value...\n",index.stop)

# Display the step parameter value
print("\nRangeIndex step value...\n",index.step)

Output

This will produce the following output −

RangeIndex...
RangeIndex(start=10, stop=30, step=2,name='data')

RangeIndex start value...
10

RangeIndex stop value...
30

RangeIndex step value...
2
