Thanks Chris,
the final version looks like this and it works:

from ftplib import FTP
ftp=FTP('10.0.0.1')
ftp.login('mike','******')
directory='/var/www/blabla/'
ftp.cwd(directory)
ftp.retrlines('LIST')
print('<- - - - - - - - - >')
file_to_change='test.php'
i=1
i=open(file_to_change,'w')
text='test'
i.write(text)
i.close()
i=open(file_to_change,'rb')
ftp.storbinary('STOR ' + file_to_change,i)
ftp.retrlines('LIST')
i.close()
