Put out and put in.

You can say that, but as I have been taught that this is grammatically wrong.

It isn't wrong.

I respect that you have been speaking English for more than 70 years, but it is a matter of grammar, so to speak, I know some native English speakers saying they don't know about English grammar.
You can't telling me that we can use past and present in one sentence or to form one sentence.
If so, just give me one more example.

The question to ask is do those verbs contradict each other?

Implicitly understanding the grammar of a language and knowing grammar terms are two different things.

I'm not trying to contradict your teachers. In fact, I might even agree with them if I knew exactly what they said.

No other examples come readily to mind.

Maybe somebody else can provide some example sentences.

John left yesterday

If so, just give me one more example, please.

John called to say he is in Berlin for the next three days.

John left yesterday

John called to say he is in Berlin for the next three days.

This is a reported speech.

I noticed that you have four photos of John on the wall.

 

[Tarheel]

@sdgsdg Two things. One, say: "That is reported speech." Two, that's a new rule. You didn't previously say anything about any restrictions.

 

[sdgsdg]

I noticed that you have four photos of John on the wall.

Sorry, I don't understand what this means.

 

[Piscean]

It's an example of a sentence that contains one past-tense verb and one present-tense verb - as you requested in post #22.

 

[sdgsdg]

But, this is also a rule.
We can't avoid the rules, and mix as we wish.
I can't say, I went to school tomorrow. I do my homework yesterday.

In this case, that's a reported speech, it's not my sentence. So I have to tell you exactly what he told me. Only thing I have to consider is the time whether at the present or in the past.
If present simple
If he said, " I go to school every day".
The reported speech will be changed to past simple.
He said that he went to school everyday.

 

[sdgsdg]

Every day , two words , sorry.

 

[Tarheel]

@sdgsdg The sentence in question is not reported speech. Also, that's not what we were discussing.

You can find the edit feature on the left at the bottom of your post.

Nobody is avoiding any rules.

You might want to check for punctuation.

 

[Piscean]

We can't avoid the rules, and mix as we wish.

There is NO rule stating that we cannot use past an Present tenses in the same sentence.

Accept it.

John left yesterday

John called to say he is in Berlin for the next three days.

This is a reported speech.

Called and said are the same.
John said he was in Berlin.
John said, " I am angry."
John said he was angry.

John said, "he lost his keys."
John said he had lost his keys.

 

[sdgsdg]

John called to say, "he will be in Berlin for the next three days."

John called/said, he would be in Berlin for the next three days.

 

[sdgsdg]

In the reported speech we transfer the present to past, and the past to past perfect.
We transfer the present perfect to past perfect, and present progressive to past progressive, and also the past progressive to perfect progressive

 

[Tarheel]

This is a reported speech.

No. For the third time it should be: "This is reported speech." (No article.)

"Called " and "said" are not the same.

 

[Tarheel]

John said, " I am angry."
John said he was angry.

You've got that one right. (The punctuation is a little off.)

 

[Tarheel]

John said, "he lost his keys."
John said he had lost his keys.

If the first one is supposed to be direct speech it should be: John said, "I lost my keys."

Every once in a while a learner explains things to us. It is rarely helpful.

 

[Tarheel]

John called to say, "he will be in Berlin for the next three days."

John called/said, he would be in Berlin for the next three days.

If the first one is supposed to be direct speech it should be: John called. He said, "I will be in Berlin for the next three days."
