pandas Creating DataFrames Create a sample DataFrame
Example
import pandas as pd
Create a DataFrame from a dictionary, containing two columns: numbers and colors. Each key represent a column name and the value is a series of data, the content of the column:
df = pd.DataFrame({'numbers': [1, 2, 3], 'colors': ['red', 'white', 'blue']})
Show contents of dataframe:
print(df)
# Output:
# colors numbers
# 0 red 1
# 1 white 2
# 2 blue 3
Pandas orders columns alphabetically as dict are not ordered. To specify the order, use the columns parameter.
df = pd.DataFrame({'numbers': [1, 2, 3], 'colors': ['red', 'white', 'blue']},
columns=['numbers', 'colors'])
print(df)
# Output:
# numbers colors
# 0 1 red
# 1 2 white
# 2 3 blue
