readline.write_history_file([filename])
Save the history list to a readline history file, overwriting any existing file. The default filename is ~/.history. This calls write_history() in the underlying library. | python.library.readline#readline.write_history_file |

For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval(), otherwise the representation is a string enclosed in angle brackets that contains the name of the typ... | python.library.functions#repr |
reprlib — Alternate repr() implementation Source code: Lib/reprlib.py The reprlib module provides a means for producing object representations with limits on the size of the resulting strings. This is used in the Python debugger and may be useful in other contexts as well. This module provides a class, an instance, and... | python.library.reprlib |
