01JAN 06:49:30.439 WARNING - Entered Zone - Operator = 5, Body Part = Body, u = 75830967.07, v = 45233540.51, w = 0.00, delta = 3

From the above line how to print Entered zone and delta

[SioSio]

If the input format is always constant, split the input data using "split".

val = input('')
l = val.split(',')
m = l[0].split('=')
n = l[5].split('=')
x = m[1]
y = n[1]
print(x,y)
 

If there is a line feed code after delta = x, the following code works.

f = open('filename')
val = f.readline()
while val:
  l = val.split(',')
  m = l[0].split('= ')
  n = l[5].split('= ')
  if ('Entered Zone' in m[0]):
      x = m[1]
      y = n[1]
      print(x,y)
  val = f.readline()
f.close
 

One space after "delta = x" followed by the next data.

f = open('filename')
val = f.readline()
f.close
val2 = val.replace(' ',',')
word = val2.split(',')
flg1 = False
flg2 = False
enterd = ''
delta = ''
i = 0
for elem in word:
    if word[i] == 'Entered':
        enterd = word[i+5]
        flg1 = True
    if flg1 == True and word[i] == 'delta':
        delta = word[i+2]
        flg2 = True
    if flg1 and flg2:
        print(enterd,delta)
        flg1 = False
        flg2 = False
    i = i + 1

FILE consists of those lines i have get the lines containing Entered Zone and print the delta value

It look like there is no line break and there is no comma only after delta = x, so it is impossible with the previous post way.
I think that After "delta = x", there will be an operation to separate by "split" with a space.
