 \subsection{Examples}
 
 The ``Hello, world'' of csv reading is
 
 \begin{verbatim}
-    import csv
-    reader = csv.reader(file("some.csv"))
-    for row in reader:
-        print row
+import csv
+reader = csv.reader(file("some.csv"))
+for row in reader:
+    print row
 \end{verbatim}
 
 The corresponding simplest possible writing example is
 
 \begin{verbatim}
-    import csv
-    writer = csv.writer(file("some.csv", "w"))
-    for row in someiterable:
-        writer.writerow(row)
+import csv
+writer = csv.writer(file("some.csv", "w"))
+for row in someiterable:
+    writer.writerow(row)
