iterate over a list of colums to print out the .value_counts()

pandas frequency table multiple columns
pandas value_counts multiple columns
pandas value_counts for all columns
pandas count occurrences in column group by
pandas groupby
pandas count specific value in column
pandas groupby value counts
pandas groupby count

I have a list of columns i want to iterate over to get the .value_counts() for each column , getting errors or the code i posted in the bottom i get no printing at all

x = [ 'call_type','date_time','FullAddress','priority']

for i in range(len(x)):

this is with one single column name

You are just generating data, but not telling your function to print the data to the console.

Add the print() function

x = ['call_type','date_time','FullAddress','priority']

for i in range(len(x)):

print value_counts for columns in a loop, You have an extra pair of square brackets in your chart_cols. Replace the first line by chart_cols = 'respondent_age respondent_gender� Iterate Over columns in dataframe by index using iloc[] To iterate over the columns of a Dataframe by index we can iterate over a range i.e. 0 to Max number of columns then for each index we can select the columns contents using iloc[]. Let’s see how to iterate over all columns of dataframe from 0th index to last index i.e.

Your solution should working, also is possible simplify:

for i in x:

Pandas, How to list available columns on a DataFrame; How to iterate over a DataFrame for item, row in df.iterrows(): print row() df[column].value_counts() # get indexes df[column].value_counts().index.tolist() # get values of occurrences to enter missing months on your dataframe with empty values on them. Iteration is a general term for taking each item of something, one after another. Pandas DataFrame consists of rows and columns so, in order to iterate over dataframe, we have to iterate a dataframe like a dictionary.

Pandas iterate row and update, The list of columns and the types in those columns the schema. age, row. Pass in a number and Pandas will print out the specified number of rows as shown in the In addition to iterrows, Pandas also has an useful function itertuples(). But it comes in handy when you want to iterate over columns of your choosing only. Dataframe class provides a member function iteritems () which gives an iterator that can be utilized to iterate over all the columns of a data frame. For every column in the Dataframe it returns an iterator to the tuple containing the column name and its contents as series.

  • please do add some sample data too which matches the counts
  • What is error here?
  • sorry i was not printing
  • @jezrael please dont vote me down , was not using print
  • @anky_91 sorry was not using print
  • can you explain why ` for i in range(len(x)): df[x[i]].value_counts()` did not work
