+Here we are trying to convert the list element stored in single quotes with
+that to stored in double quotes. Also the output is string as in list elements are by default enclosed in single quotes.

+
+# Either define list of columns or directly store from df.columns
+
+# List df_columns contains the columns of the dataframe
+df_columns = ['Column 1','Column 2','Column 3','Column 4','Column 5','Column 6']
+
+# Empty string to Store Result
+df_columns_string = ''
+
+
+# Traversing elements and adding double quotes
+for i in df_columns:
+
+	# For the last element we do not need to append comma
+	if i == df_columns[-1]:
+
+		# Here element is appended with double quotes
+		ele = '"' + i + '"'
+
+		# Added in final list
+		# Not Added comma as it is the last element
+		df_columns_string = df_columns_string + ele

+	else:
+		# Here element is appended with double quotes
+		ele = '"' + i + '"'
