How to lowercase selected item in a list-CodePudding

I have

x= ['AA', 'BB', 'CC']

and I want to lower case only 'BB'.

CodePudding user response：

To transform a string to lowercase, you use

string.lower()

To answer your question, use

x[1] = x[1].lower()

CodePudding user response：

To lower case only 'BB' in the list x, you can use a list comprehension with an if condition to check if the element is equal to 'BB'.

Here is how you can do that:

x = ['AA', 'BB', 'CC']

# Use a list comprehension with an if condition to lower case only 'BB'
x = [element if element != 'BB' else 'bb' for element in x]

# Print the modified list
print(x)
# Output: ['AA', 'bb', 'CC']

Hope this helps!

CodePudding user response：

perhaps try

` x = ['AA', 'BB', 'CC']

Str = x[1]

print(Str.lower())

#0 = AA, 1 = BB, 2 = CC

use 0 1 or 2 with x[NUMBER]

I hope this works for you!!
