How to find lowercase first letter in word list, and change them into uppercase

I want to find out if any of those names start with lowercase and, if they do, change it to uppercase.

unknown_list = ('toby', 'James', 'kate', 'George', 'rick', 'Alex', 'Jein', 'medelin')

One small reminding is that the parentheses you're using make your unknown_list a tuple. Tuples are immutable.

If you just want to capitalize everything in the list you can do this

unknown_list = ['toby', 'James', 'kate', 'George', 'rick', 'Alex', 'Jein', 'medelin']
capLs = []
for i in unknown_list:
  capLs.append(i.capitalize())
print(capLs)

maybe you can do like this:

x = ['toby', 'James', 'kate', 'George', 'rick', 'Alex', 'Jein', 'medelin']
x = [name.title() for name in x]

The capitalize() method can do this easily:

>>> unknown_list = ('toby', 'James', 'kate', 'George', 'rick', 'Alex', 'Jein', 'medelin')

>>> new_list = [x.capitalize() for x in unknown_list]
>>> new_list
['Toby', 'James', 'Kate', 'George', 'Rick', 'Alex', 'Jein', 'Medelin']

Note that's creating a new list but you could just as easily assign back to the original variable if you want to overwrite it.

You used to chr() and ord()

chr(97) is 'a', chr(65) is 'A'

and

ord('a') is 97 , ord('A') is 65 as int

test case:

for name in unknown_list:
    if ord(name[0]) >=97 and ord(name[0]) <=122:
        tmp = ord(name[0]) - 32
             print(chr(tmp))

But, easier way

name = 'james'
print(name.capitalize())

It can print 'James'

Tuples are immutable so you cannot change them but if you change unknown_list into a list then you are able to do that. You should use the .capitalize() function!

Here is the short version.

x = ['toby', 'James', 'kate', 'George', 'rick', 'Alex', 'Jein', 'medelin']
x = [name.capitalize() for name in x]

And the long version.

x = ['toby', 'James', 'kate', 'George', 'rick', 'Alex', 'Jein', 'medelin']
for index, name in enumerate(x):
     x[index] = name.capitalize()

The main idea in both is that you capitalize every name in order to achieve your goal.
