program error ? - Xraydelta - Apr-14-2020
[Please excuse in advance the quality of my English ...I'm French
]Hello,
I'm new on this forum and begin in python programming;
I recently had an exercise that involved completing a program to determine the value of "t" to the nearest 0.1 at which point "C" was less than 0.2 with C = 20*exp(-0,1*t).
So I created the following program and don't really understand why it doesn't work
:from math import*
t = 0
C = 20*exp(-0.1*t)
while C >= 0.2 :
t += 0.1
print(t)
If you could help me then
knowing that I did put the indentation in the fifth line...

C needs to be calculated within the loop. Otherwise, C stays the same even though t changes because C is not recalculated.
Also, for the future, use the python tags (click on the Python button on the toolbar) so the code is displayed better.
