格式化打印语句pandas df

Question

I have a pandas data frame like so:

[in]print(lang_sorted)

[out]
      frequency
lang           
en          585
ar          179
es          147
ja          114
pt          113
und         109
tr           82
fr           43
ko           21

How can I print the data frame to a text file without any headers or spaces- so that the format is 'lang,freq'\\n where each line is a new line with no spaces or breaks in the file (and no ' ')?

I tried: print("{},{}".format(lang_sorted)) but this threw an error: IndexError: tuple index out of range and also: print(lang_sorted.applymap("{0:.2f}".format)) but this just turned my frquencies to floats.

The file I am printing this into is organized like such:

# Create the twitter analytics text file
with io.open("twitter_analytics.txt","w",encoding='utf8') as twitter_analytics:    
    # Number of events
    print(len(data))
    # Number of tweets
    print(len(tweets))
    # Frequency of tweets by language
    print("{},{}".format(lang_sorted))
    twitter_analytics.close()

Answer 1

Use DataFrame.to_csv .

df.to_csv('your-file.csv')

Or without headers:

df.to_csv('your-file.csv', header=False)
