The **`upper`** method in Python converts all the characters of a string to uppercase. 

# 
## Syntax

```python
string_A.upper()
```
## Parameter

The function takes in no parameters.
## Return value

The function returns a new string that is created from `string_A` by converting all the characters of `string_A` to uppercase.

> If there are no lowercase characters in `string_A`, then the original string is returned.


string_A = "eduCativE"
print(string_A, " upper() -> ", string_A.upper())

In the code above, we create an `eduCativE` string and call the `upper` method, which converts all of the characters of the string to uppercase and returns `EDUCATIVE`.


string_A = "Educative"
string_B = "EDUCATIVE"

print("String_A = ", string_A)
print("String_B = ", string_B)

print("String_A == String_B ", string_A == string_B)
print("String_A.upper() == String_B.upper() ", string_A.upper() == string_B.upper())

In the code above, we create two strings, `Educative` and `EDUCATTIVE`. We get `False` when we compare the two strings because the cases of the strings are different.

 We then use the `upper` method to convert both strings to uppercase. After both strings are converted to uppercase, we get `True` when we check whether the two strings are the same.
