Hello,
with python 2.7 I encounter the following problem:
I have created the following sample script:
import pdb
def function_1(number):
 stack_1 = number
 function_2(stack_1)
 
def function_2(number):
 stack_2 = number + 1
 function_3(stack_2)
 
def function_3(number):
 stack_3 = number + 1
 pdb.set_trace()
 print stack_3
 
function_1(1)
This is what I have done in the pdb session:
> c:\tst_pdb.py(14)function_3()
-> print stack_3
(Pdb) l
 9 function_3(stack_2)
 10
 11 def function_3(number):
 12 stack_3 = number + 1
 13 pdb.set_trace()
 14 -> print stack_3
 15
 16 function_1(1) [EOF]
(Pdb) stack_3
3
(Pdb) !stack_3 = 177
(Pdb) !print stack_3
177
(Pdb) u
> c:\tst_pdb.py(9)function_2()
-> function_3(stack_2)
(Pdb) l
 4 stack_1 = number
 5 function_2(stack_1)
 6
 7 def function_2(number):
 8 stack_2 = number + 1
 9 -> function_3(stack_2)
 10
 11 def function_3(number):
 12 stack_3 = number + 1
 13 pdb.set_trace()
 14 print stack_3
(Pdb) !print stack_2
2
(Pdb) !stack_2 = 144
(Pdb) !print stack_2
144
(Pdb) d
> c:\tst_pdb.py(14)function_3()
-> print stack_3
(Pdb) l
 9 function_3(stack_2)
 10
 11 def function_3(number):
 12 stack_3 = number + 1
 13 pdb.set_trace()
 14 -> print stack_3
 15
 16 function_1(1) [EOF]
(Pdb) stack_3
3
(Pdb) u
> c:\tst_pdb.py(9)function_2()
-> function_3(stack_2)
(Pdb) !print stack_2
2
(Pdb)
I walked through the stack and changed the values of the variables stack_x but the values weren't saved when I moved one frame up/down
