Here is how to create a pandas DataFrame from a dictionary in Python.

import pandas

# Create a sample dictionary of str:list
mydata = {'Celsius':[10, 20, 30], 
    'Fahr':[4, 5, 6], 'Kelvin':[7,8,9]} 

# Create dataframe from the dictionary
df = pandas.DataFrame(mydata) 

# Print out the dataframe
print(df) 

Copy & Run

Since the structure of a pandas dataframe is similar to that of a Python dictionary, it is enough to provide the dictionary as an argument to the DataFrame class and we end up with a dataframe object. Notice that the dictionary keys are transformed into dataframe columns names.
