Please provide the code with comments as well

Find the IEEE 754 representation of numbers in the table i.e. create this table and fill it out in Jupyter notebook with the necessary conversions, the sign bits, exponents and mantissa. Use the Latex capability of the markdown cells in Jupyter notebook. Then show that the results are correct using the Python built in conversions for the binary and decimal types for at least one case each for decimal to binary and binary to decimal respectively. DecimalBinary Scientific notation Sign bitExponent Mantissa 101101 25 11.105 10011.01101 Your choice

Explanation / Answer

ANSWER :

def createTableFile (out_tb1, dataList, fields2Add, arcpy):  
Requires:
out_tb1 output feature class name "c:/temp/myfile.dbf"
dataList a list of lists of data eg.
[[data list 1],[data list 2]...[data list n]]
or [[data list 1]]
arcpy the Geoprocessor Object
Returns:
Create the output table and returns a message (msg)
'''  
fulname = os.path.split(out_tb1)  
out_folder = fulname[0].replace("\","/")  
out_fname = fulname[1].replace(" ", "_")  
outFullName = out_folder + "/" + out_fname  
message = " "  
try:  
arcpy.CreateTable_management(out_folder, out_fname)  
message += " Creating: " + str(out_fname)  
except:  
message += " Failed to create feature class: " + arcpy.GetMessages()  
return message  
for aField in fields2Add:  
message += " Adding field: " + str(aField)  
try:  
arcpy.AddField_management(outFullName, aField[0], aField[1], aField[2], aField[3])  
except:  
message += " Failed to add field: " + aField[0] + " " +arcpy.GetMessages()
try:  
cur = arcpy.InsertCursor(out_tb1)  
except:  
message += "Failed to create cursor"  
return message  
anID=0  
for i in range(0,len(dataList)):  
values = dataList[i]  
a_row = cur.newRow()  
for j in range(0, len(values)):  
a_row.setValue(fields2Add[j][0],values[j])  
cur.insertRow(a_row)  
del a_row  
del cur  
message += " Processing complete"  
return message  
if __name__ == "__main__":  
import sys, os  
import arcpy  
arcpy.env.overwriteOutput = True  
outDBF = "C:/temp/testdbf.dbf"   
if os.path.exists(outDBF):  
os.remove(outDBF)   
dataList = [[1,1,1,"a"],[2,2,2,"b"],[3,3,3,"c"],[4,4,4,"d"],[5,5,5,"e"]]  
fields2Add = [["X", "double", 14, 7],  
["Y", "double", 14, 7],  
["Z", "double", 14, 7],  
["TextFld", "text", 20,""]]  
message = createTableFile(outDBF, dataList, fields2Add, arcpy)  
print message
