python - watch function calls and variable values? -


how can watch functions called , variable values in python script?

i have discovered uncertainties package python, , want figure out how works can explain boss.

basically, can't see how uncertainties calculated. because don't know how python works yet.

for starters, how can see how c calculated?

import uncertainties uncertainties import ufloat  = ufloat(1,3) b = ufloat(2,4)  c = + b #how work??  print c

you might take @ python debugger: http://docs.python.org/2/library/pdb.html

as may know, debugger designed let watch parts of program move during execution.

you might want take @ source code of uncertainties package @ https://github.com/lebigot/uncertainties/

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
