Answer:
Explanation:
Here is the set of natural numbers between 100 and 450, using the ellipsis button:
Y = {100, 101, 102, ..., 449, 450}
The ellipsis button (...) represents all of the natural numbers between 102 and 449, inclusive.
Here is an example of how to use the ellipsis button to write a set in Python:
import pandas as pd
# Create a list of natural numbers between 100 and 450
Y = list(range(100, 451))
# Create a Pandas DataFrame from the list
df = pd.DataFrame(Y, columns=["Y"])
# Print the first 5 rows of the DataFrame
print(df.head())
