Enable handle of csv, xls and xlsx files getting column header
Project description
The PyHeaderFile helps the work with files that have extensions csv, xls and xlsx.
This project aims reading files over the header (column names). With this module we can handle Csv, Xls and Xlsx files using same interface. Thus, we can convert extensions, strip values in lines, change cell style of Excel files, read a specific Excel file, read an specific cell and read just some headers.
Install
pip install pyheaderfile
How to use
Class csv
Read csv
file = Csv(name=’file.csv’) for row in file.read(): print row
Set Header
file.header = ['col1', 'col2','col3']
Create csv
file = Csv(name='filename.csv', header=['col1','col2','col3'])
Write list csv
file.write(['col1','col2','col3'])
Write dict csv
file.write(dict(header=value))
Class Xls
Read xls
file = Xls(name=’file.xls’) for row in file.read(): print row
Set Header
file.header = ['col1', 'col2','col3']
Create xls
file = Xls(name='filename.xls', header=['col1','col2','col3'])
Write list
file.write(['col1','col2','col3'])
Write dict
file.write(dict(header=value))
Class Xlsx
Read
file = Xlsx(name=’file.xlsx’) for row in file.read(): print row
Set Header
file.header = ['col1', 'col2','col3']
Create file
file = Xlsx(name='filename.xlsx', header=['col1','col2','col3'])
Write list
file.write(['col_val1','col_val2','col_val3'])
Write dict
file.write(dict(header=value))
Save file
file.save()
Tricks
Modifying extensions, name and header
q = Xls() x = Xlsx(name='filename.xlsx') x.name = 'ugly file name' x.header = ['col1', 'col2','col3'] q(x)
Guess file type
To guess what class you need to open just use:
- ::
filename = ‘test.xls’ my_file = guess_type(filename)
And for a SUPERCOMBO you can guess and convert everything!
- ::
my_file = guess_type(filename) convert_to = Xls() my_file.name = ‘beautiful_name’ my_file.header = [‘col1’, ‘col2’,’col3’] convert_to(my_file) # now yout file is a xls file ;)
