python - Print very long string completely in pandas dataframe

Question

I am struggling with the seemingly very simple thing.I have a pandas data frame containing very long string.

df = pd.DataFrame({'one' : ['one', 'two', 
      'This is very long string very long string very long string veryvery long string']})

Now when I try to print the same, I do not see the full string I rather see only part of the string.

I tried following options

• using print(df.iloc[2])
• using to_html
• using to_string
• One of the stackoverflow answer suggested to increase column width by using pandas display option, that did not work either.
• I also did not get how set_printoptions will help me.

Any ideas appreciated. Looks very simple, but not able to get it!

You can use options.display.max_colwidth to specify you want to see more in the default representation:

In [2]: df
Out[2]:
                                                 one
0                                                one
1                                                two
2  This is very long string very long string very...

In [3]: pd.options.display.max_colwidth
Out[3]: 50

In [4]: pd.options.display.max_colwidth = 100

In [5]: df
Out[5]:
                                                                               one
0                                                                              one
1                                                                              two
2  This is very long string very long string very long string veryvery long string

And indeed, if you just want to inspect the one value, by accessing it (as a scalar, not as a row as df.iloc[2] does) you also see the full string:

In [7]: df.iloc[2,0]    # or df.loc[2,'one']
Out[7]: 'This is very long string very long string very long string veryvery long string'
