Write a function Remove_Lowercase() that accepts two file names, and copies all lines that do not start with lowercase letter from the first file into the second file.

Let the file "file1.txt" include the following sample text:

Dew on petals, morning's gift.
silent moon, silver glow.
Winds whisper, secrets shared.
rain's embrace, earth's renewal.

def Remove_Lowercase(input_file, output_file):
    input_file = open(input_file, 'r')
    output_file = open(output_file, 'w')
    for line in input_file:
        if line.strip() and line[0].isupper():
            output_file.write(line)
    input_file.close()
    output_file.close()

input_file = 'file1.txt'
output_file = 'file2.txt'
Remove_Lowercase(input_file, output_file)

The file "file2.txt" includes following text:

Dew on petals, morning's gift.
Winds whisper, secrets shared.
