A quick and dirty solution would be to convert it to a string

print('\t'.join(data_all2.columns))

would cause all of them to be printed out separated by tabs Of course, do note that with 102 names, all of them rather long, this will be a bit hard to read through

You can globally set printing options  I think this should work  Method 1  pd set option  display max columns   None  pd set option  display max rows   None   Method 2  pd options display max columns   None pd options display max rows   None  This will allow you to see all column names  amp  rows when you are doing  head    None of the column name will be truncated   If you just want to see the column names you can do  print df columns tolist

If you just want to see all the columns you can do something of this sort as a quick fix  cols   data all2 columns   now cols will behave as a iterative variable that can be indexed  for example  cols 11 20

What worked for me was the following   pd options display max seq items   None   You can also set it to an integer larger than your number of columns

In the interactive console  it s easy to do   data all2 columns tolist     Or this within a script   print data all2 columns tolist

To get all column name you can iterate over the data all2 columns   columns   data all2 columns for col in columns      print col   You will get all column names  Or you can store all column names to another list variable and then print list

Not a conventional answer  but I guess you could transpose the dataframe to look at the rows instead of the columns  I use this because I find looking at rows more  intuitional  than looking at columns   data all2 T   This should let you view all the rows  This action is not permanent  it just lets you view the transposed version of the dataframe   If the rows are still truncated  just use print data all2 T  to view everything

To obtain all the column names of a DataFrame  df data in this example  you just need to use the command df data columns values  This will show you a list with all the Column names of your Dataframe  Code   df data pd read csv     input data csv   print df data columns values    Output     PassengerId   Survived   Pclass   Name   Sex   Age   SibSp   Parch   Ticket   Fare   Cabin   Embarked

The easiest way I ve found is just list df columns   Personally I wouldn t want to change the globals  it s not that often I want to see all the columns names

User · Answer

This will do the trick  Note the use of display   instead of print   with pd option context  display max rows   5   display max columns   None        display my df    EDIT   The use of display is required because pd option context settings only apply to display and not to print
