     '11' or '12' in i is evaluated like this

     ('11') or ('12' in i)-

     So, the first part is always truthy. That is why all of them are printed. In the second case,

     ('11') and ('12' in i)-

     Here, first part is always Truthy, so it prints only the items which contain 12. You might want do

     if '11' in i and '12' in i:-

     or

     if all(item in i for item in ('11', '12')):-

     To have or condition, you can use any function, like this

     if any(item in i for item in ('11', '12')):-

   • Python | Splitting operators in String

     Sometimes we have a source string to have certain mathematical statement for computations and we need to split both the numbers and operators as a list of individual elements. Let’s discuss certain ways in which this problem can be performed. 

     Method #1 : Using re.split() This task can be solved using the split functionality provided by Python regex library which has power to split the string according to certain conditions and in this case all numbers and operators. 

     Python3

     # Python3 code to demonstrate working of# Splitting operators in String# Using re.split()import re # initializing string test_str = "15 + 22 * 3-4 / 2" # printing original string print("The original string is : " + str(test_str)) # Using re.split()# Splitting operators in Stringres = re.split(r'(\D)', test_str) # printing result print("The list after performing split functionality : " + str(res))-

     Output : 

     The original string is : 15+22*3-4/2 The list after performing split functionality : [’15’, ‘+’, ’22’, ‘*’, ‘3’, ‘-‘, ‘4’, ‘/’, ‘2’]

     Time Complexity: O(n) where n is the length of the input string.

     Auxiliary Space: O(n)

     Method #2 : Using re.findall() This Python regex library function also can...

     You could use a generator expression to perform the filtering first

     >>> min(i for i in a if i > 5)6-

     This avoids having to create a list in memory if you had min evaluate the result of a list comprehension

   • Python use multiple operators in a boolean expression

     Top Answer

     Answered Feb 13, 2020 · 1 votes

     This is the code given by you.

     a = 1b = 1c = 2-if a == b == c == 1: print('All equal!')else: print('At least one variable is not equal to others')

     Let's understand what it means.a==b==c==1 is evaluated to True only when all three of them are equal to 1. Else evaluated to False. a==b==c is evaluated as a==b and b==c and c==a.

     To get what you wanted you have to do this.

     if a==b==c==1: print('All are equal')elif (a==b) or (b==c) or (c==a): print('At least one variable is not equal to others')else: print('none of them are equal')

     Now for analysis the second you provided with bytcode.

     a = 1;b =2;c =1.5a<b<c-

     a<b<c is evaluated as a<b and b<c in your case this is 1<2 and 2<1.5 which is evaluated to False. 1<2 is evaluated to True and 2<1.5 is evaluated to False. True andFalseis evaluated toFalse`.

     Byte code:

     In [2]: a=1;b=2;c=1.5-In [3]: dis.dis('a<b and b<c') 1 0 LOAD_NAME 0 (a) 2 LOAD_NAME 1 (b) 4 COMPARE_OP 0 (<) 6 JUMP_IF_FALSE_OR_POP 14 8 LOAD_NAME 1 (b) 10 LOAD_NAME 2 (c) 12 COMPARE_OP 0 (<) >> 14 RETURN_VALUE

     6 JUMP_IF_FALSE_OR_POP 14 What this line tells us is jump to line 14 if false.In logical and False and any_bool_value

     always evaluates to False.

     Now if 6 JUMP_IF_FALSE_OR_POP 14 is True then it continues executing 8 to 14.

     And it's safe to use Multiple boolean operators in a single expression.
