sentence = "to be or not to be"

for word1 in s:
    for word2 in s:
        result.append(word1 + " " + word2)
       
result = set(result)
result = list(result)
result.sort()


for item in result:
    if item in sentence:
        result.remove(item)
        
for item in result: 
    if " ".join(item.split()[::-1]) in sentence:
        result.remove(item)
        
for item in result:
    spl = item.split()
    if (spl[0] == spl[1]) and (sentence.count(spl[0]) < 2):
        result.remove(item)
        
for item in result:
    spl = item.split()
    dup = spl[1] + " " + spl[0]
    if dup in result:

result.insert(0, "be be")   
for item in result:
    print(item)

Answer 1

s = input().split()
n = len(s)


st = set()
for i in range(n):
    for j in range(n):
        if i != j-1 and i != j and i != j+1:
            if i > 0 and s[i-1] == s[j]:
                continue
            if i < n-1 and s[i+1] == s[j]:
                continue
            if j > 0 and s[i] == s[j-1]:
                continue
            if j < n-1 and s[i] == s[j+1]:
                continue
            st.add(s[i]+' '+s[j] if s[i]<s[j] else s[j]+' '+s[i])
            
for item in sorted(st):
    print(item)
