For loop if - not matching string even though string exists

Question

The below code does not match in all the if statements.
I would like to know what makes the if statement match in the 2nd for loop, but not in the 1st and 3rd for loop?

for line in x:
    if '0.0.0.0/0' and 'A' in line:
        y = re.findall(r'\b\d{2,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b', str(line))

These are the lines in x.
No lines get matched but correct value still goes into y because it is the only one which matches regex.
0 ADS 0.0.0.0/0 41.222.225.255 0
1 ADC 41.222.225.255/32 197.242.206.100 pppoe-out1 0
2 ADC 172.20.0.0/24 172.20.0.1 LAN 0

gw = []
for line in x:
        if y and '/32' in line:
        gw.append(str(line).split()[4])

Line in x which gets matched as expected.
I have not shown the other lines which do not get matched
1 ADC 41.222.225.255/32 197.242.206.100 pppoe-out1 0

mtu = []
for line in x:
    print line
    if str(gw) in line:
        mtu.append(re.findall(r'actual-mtu=\d{1,4}\s*', str(x)))

Line in x which does not get matched.

`'0.0.0.0/0' and 'A' in line` does not test if either value is in the line. `'A' in line` does, but boolean operators don't understand english grammar. `'0.0.0.0/0'` is tested separately, and always true because it is a non-empty string. — Martijn Pieters, Jun 16 '17 at 08:49
In this case, I'd use `if '0.0.0.0/0' in line and 'A' in line:` — Martijn Pieters, Jun 16 '17 at 08:55
