I have a Excel file 'test.xls' file which I could read in as following:
df= pd.read_excel('test.xls',sep='\t',header=1)
I checked df and found there is a column zip_code which contain zip code like 00051, 00123, but the first 0 was cut off while the system read in the excel file.
So that column will be 51, 123. How could I keep the first zeros intact while reading the file? Thanks. Found solution as I posted below.
