python how to programmatically get line number of class definition

If you define the class, line numbers could be exposed like this:

class MyClass:
   def test_01(self):
   assert 1
_classline_ = inspect.currentframe().f_code.co_firstlineno
_thisline_ = inspect.currentframe().f_lineno

This requires static analysis code I wrote for the xdoctest module. I'm not sure it solves 100% of the cases, but I think it is more robust than a regex search.

def static_calldefs(modpath):
   from xdoctest
import static_analysis as static
calldefs = dict(static.parse_calldefs(fpath = modpath))
return calldefs

def get_object_lineno(obj):
   try:
   # functions just
lineno = obj.__code__.co_firstlineno
except AttributeError:
   attrname = obj.__name__
modpath = sys.modules[obj.__module__].__file__
calldefs = static_calldefs(modpath)
ub.modpath_to_modname(modpath)
calldef = calldefs[attrname]
lineno = calldef.lineno
return lineno

01 Python how to programmatically get line number of class definition ,Python is a high level general purpose programming language with wide ranges of uses, from data science, machine learning, to complex scientific computations and various other things. One of the simplest of languages to get started with and as powerful as to power intelligent machines. One of the best things about python is that it is easier to get started with.,If you define the class, line numbers could be exposed like this:,inspect.findsource(test.dummy)[1] provides the line number via regex search in the source file (rather slow).

If you define the class, line numbers could be exposed like this:

class MyClass:
   def test_01(self):
   assert 1
_classline_ = inspect.currentframe().f_code.co_firstlineno
_thisline_ = inspect.currentframe().f_lineno

This requires static analysis code I wrote for the xdoctest module. I'm not sure it solves 100% of the cases, but I think it is more robust than a regex search.

Setting dynamically created EditTexts bottom line color programatically?,We can get the number of commits by counting the lines, but we must ensure that only one-line is printed per commit. This is possible using the --pretty=oneline git log formatter:,Finally, we can count the number of lines by piping our git log output from stdout to the wc shell executable. By default, this executable will count the number of characters, but can be configured to count lines using the -l command-line option:,cypher query to get all relationship for a node doesn't return graphical representation in 3.1

// Integrate Sniffy to your test using @Rule annotation and a QueryCounter field

First, we need a file to read from. So, create a file inside Jupiter notebook using the magic function as shown below:

% % writefile geeks.txt
Hello, I am Romy
I am a content writer at GfG
Nice to meet you
Hello, hii all fine

Output:

'Hello, I am Romy\nI am a content writer at GfG\nNice to meet you\nHello, hii all fine'

Output:

Number of lines in file is: 4['Hello, I am Romy\n',
   'I am a content writer at GfG\n',
   'Nice to meet you\n',
   'Hello, hii all fine']

The java.lang.StackTraceElement.getLineNumber() method returns the line number of the source line containing the execution point represented by this stack trace element.,This method returns the line number of the source line containing the execution point represented by this stack trace element, or a negative number if this information is unavailable.,Following is the declaration for java.lang.StackTraceElement.getLineNumber() method,The following example shows the usage of java.lang.StackTraceElement.getLineNumber() method.

Following is the declaration for java.lang.StackTraceElement.getLineNumber() method

public int getLineNumber()

package com.tutorialspoint;

import java.lang.*;

public class StackTraceElementDemo {

   public static void main(String[] args) {
      function1();
   }

   public static void function1() {
      new StackTraceElementDemo().function2();
   }

   public void function2() {
      System.out.print("line number : ");
      System.out.print(Thread.currentThread().getStackTrace()[1].getLineNumber());
   }
}

Let us compile and run the above program, this will produce the following result −

line number: 17

Note that the end positions are not required by the compiler and are therefore optional. The end offset is after the last symbol, for example one can get the source segment of a one-line expression node using source_line[node.col_offset : node.end_col_offset].,Each instance of a concrete class has one attribute for each child node, of the type as defined in the grammar. For example, ast.BinOp instances have an attribute left of type ast.expr.,One for clause in a comprehension. target is the reference to use for each element - typically a Name or Tuple node. iter is the object to iterate over. ifs is a list of test expressions: each for clause can have multiple ifs.,lambda is a minimal function definition that can be used inside an expression. Unlike FunctionDef, body holds a single node.

node = ast.UnaryOp()
node.op = ast.USub()
node.operand = ast.Constant()
node.operand.value = 5
node.operand.lineno = 0
node.operand.col_offset = 0
node.lineno = 0
node.col_offset = 0

node = ast.UnaryOp(ast.USub(), ast.Constant(5, lineno = 0, col_offset = 0),
   lineno = 0, col_offset = 0)
