pandas create empty dataframe
# Basic syntax:
import pandas as pd
empty_dataframe = pd.DataFrame()
# Create empty dataframe with column names
empty_dataframe = pd.DataFrame(columns=['your', 'column', 'names'])
# Create empty dataframe with row names
empty_dataframe = pd.DataFrame(index=['your', 'row', 'names'])
empty dataframe
newDF = pd.DataFrame() #creates a new dataframe that's empty
newDF = newDF.append(oldDF, ignore_index = True) # ignoring index is optional
# try printing some data from newDF
print newDF.head() #again optional

df = pd.DataFrame(columns=['a', 'b', 'c'])

python pandas create an empty dataframe with columns and data types
#Create empty DataFrame with specific column names & types
df = pd.DataFrame({'Courses': pd.Series(dtype='str'),

'Discount': pd.Series(dtype='float')})
# Using NumPy
dtypes = np.dtype(

("Fee", int),
("Duration", str),
("Discount", float),
('date',np.datetime64)
]
)
df = pd.DataFrame(np.empty(0, dtype=dtypes))
