如何在python中返回列表的第N位数字？

Question

X = [1,4,5,10,23,2,5,7,19]

I want to know the digit Nth of the list...

Example:

def func(n):
    print(nth digit of X)

def func(7):
print(7th digit of X)
Output = 3

Don't need to be a function...just the method to reach to solution of the problem: function returns nth digit of a list

Answer 1

You can convert the list to a str, and then the indexing would work

x_str = ''.join([str(i) for i in x])  # x_str = "145102325719" 
# x_str[idx] would return the digit

Answer 2

x = [1,4,5,10,23,2,5,7,19]

def func(x, n):
    return ''.join(map(str, x))[n-1]

print(func(x, 7))

Prints:

3
