Search and replace a target within a project
You can search for a text string within a project, use different scopes to narrow your search process, exclude certain items from your search, find usages and occurrences.
Find the search string in a project
From the main menu, selectCtrl+Shift+F.
In the search field, type your search string. Alternatively, in the editor, highlight the string you want to find and press Ctrl+Shift+F. PyCharm places the highlighted string into the search field.
To see a list of your previous searches, press Alt+Down.
If you need, specify the additional options.
PyCharm lists the search strings and files containing them.
To do a multi-line search, click the icon to enter a new line, and press Ctrl+Alt+Down/Ctrl+Alt+Up to browse through occurrences.
Check the results in the preview area of the dialog where you can replace the search string or select another string, press Ctrl+Shift+F again and start a new search.
If you need to see the list of occurrences in a separate tool window, click Open in Find Window. You can use this window and its options to group the results, preview them, and work with them further.
Narrow your search
You can use different options in the Find in Path dialog to adjust your search process.
Select options such as Words or Match case to find the exact word in a project, or match the letter case.
With Regex checkbox selected, PyCharm automatically escapes special regex symbols with backslash
\when you search for a text string that contains them.
For more details on regex, refer to the search with regex documentation.
Click the icon to filter your search. For example, you can filter the search to omit comments or search only in comments instead.
Select one of the displayed options such as Module or Directory to limit your search. Moreover, you can select the Scope option that offers you a list of predefined scopes for your search.
For example, you can limit your search only to the open files in your project.
If you work without tabs, the scope Recently Viewed Files or Recently Changed Files option might become quite useful. You can also create your own custom scope, click the Browse icon () to open the Scopes dialog.
Search in the specific file types
Use the File Mask option to narrow your search to a specific file type. You can select the existing file type from the list, add a new file type, or add an additional file mask syntax to search for file types with certain patterns.
In the Find in Path dialog, select the File Mask checkbox and from the list of file types, select the one you need.
PyCharm limits its search to the specified type.
If you don't find the file type you need in the list, enter your file type in the File Mask field.
Other wildcards besides
*are supported. You can also specify several file types by separating them with a comma.
Search for usages in a project
You can search for usages of a symbol in your whole project or in a scope that you set.
Select the symbol for which you want to find usages. Note that you can extend your search to file usages as well.
From the main menu selectAlt+F7.
Check the results in the Find tool window.
You can also pull out the results from the previous Find Usages actions. From the main menu, select and the usage query.
While in the Find tool window, you can use the Preview area to check the places where the usages were found, to see a call hierarchy for methods, data flow for fields, and so on.
If PyCharm doesn't return any results, it will display a message suggesting to opt for more options. You can follow the link or press Ctrl+Shift+Alt+F7 to open the Find Usages dialog where you can set a new scope for your search.
For example, you can set your search scope to production files only or to only open files.
To set a custom scope, click .
When you are done setting a new scope, click Find.
If you want PyCharm to show you usages of the selected symbol in the separate window, press Ctrl+Alt+F7. You can use this window for quick navigation.
Press the same shortcut again to see the usages in the default scope.
Disable automatic highlighting of usages
When you place the caret at a symbol, the IDE highlights all usages of this symbol in the current file. Use the F3 and Shift+F3 shortcuts to navigate between highlighted symbols.
If necessary, you can disable the automatic highlighting.
When the automatic highlighting is disabled, place the caret at the necessary symbol and press Ctrl+Shift+F7. This will highlight all usages of the symbol in the current file.
Replace the search string in a project
Press Ctrl+Shift+R to open the Replace in Path dialog.
In the top field, enter your search string. In the bottom field, enter your replacement string.
For example, if you want to replace a variable name with a new name for a large project, use the replace in path instead of rename refactoring since your variable can appear in the config files as well.
Click one of the available Replace commands.
