Python in a Nutshell

break, b

Synopsis

break [ location [ ,condition ] ]

break without arguments lists currently defined breakpoints and the number of times each breakpoint has triggered. With an argument, break sets a breakpoint at the given location. location can be a line number or a function name, optionally preceded by filename: to set a breakpoint in a file that is not the current one or at the start of a function whose name is ambiguous (i.e., a function that exists in more than one file). When condition is present, condition is an expression to evaluate (in the debugged context) each time the given line or function is about to execute; execution breaks only when the expression returns a true value. When setting a new breakpoint, break returns a breakpoint number, which you can then use to refer to the new breakpoint in any other breakpoint-related pdb command.
