pandas create dataframe with header

Comment

# Basic syntax:
import pandas as pd
data_frame = pd.read_csv("test.txt", sep='\t', names=['Name1', 'Name2', 'Name3'])
# Where:
#	- Name, Age, and Gender will be the header
# Note:
#	- If the dataset already has a header that you want to overwrite, add the
#		parameter header=0
#	- If you pass fewer names than there are columns in the dataset, the names
#		will be assigned to the last columns

# Example usage:
# Say you have a tab-delimited file with the following contents and want to
# load it with a custom header:
One  Two  Three   Four
1      2      3      4
1      2      3      4
1      2      3      4

# You could do, e.g.:
df = pd.read_csv("Numbers.tsv", sep="\t", names=['Twos', 'Threes', 'Fours'], header=0)
print(df)
-->    Twos  Threes  Fours
	1     2       3      4
	1     2       3      4
	1     2       3      4
# Note:
#	- Because I passed header=0, the original header was omitted
#	- Because I passed fewer names than there are columns, the first column was
#		left without a name
