https://stackoverflow.com/questions/3389574/check-if-multiple-strings-exist-in-another-string You can use any: if any(x in str for x in a): Similarly to check if all the strings from the list are found, use all instead of any. How to drop duplicates ? pandas.DataFrame.drop_duplicates...
If your data along the x-axis (or combination of x & y in the case of 3D charts) has duplicates you have three options: Specify a group, which will create series for each group Specify an aggregation, you can choose from one of the following: Count, First, Last, Mean, Median, Min...
drop_duplicates() chrom_orfs = chrom_orfs.merge(restrictedstarts) # inner merge acts as a filter if chrom_orfs.empty: if opts.verbose > 1: logprint('No ORFs found on %s' % chrom_to_do) return failure_return inbams = [pysam.Samfile(infile, 'rb') for infile in opts.bamfiles] gnd...
Note that the column raises a ValueError if a column with the specified name is already contained in the DataFrame unless the allow_duplicates parameter is set to `True`. We passed the following 3 parameters to the DataFrame.insert() method: The insertion index. Indices are zero-based, so ...
Thus, we have eliminated any duplicate columns that might exist in our data frame using theconcatfunction and thedrop_duplicates()function. To better understand this concept, you can learn about the following topics. Concatfunction in Pandas. ...
