Demonstrates how to compress and decompress a string. Chilkat2-Python

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

sb = chilkat2.StringBuilder()

for i in range(1,21):
    sb.Append("This is the original uncompressed string.\r\n")

compress = chilkat2.Compression()
compress.Algorithm = "deflate"
# Indicate that the utf-8 byte representation of the string should be compressed.
compress.Charset = "utf-8"

# compressedBytes is a memoryview
compressedBytes = compress.CompressString(sb.GetAsString())

# If the compressed data is desired in string format, then get the base64 representation of the bytes.
compress.EncodingMode = "base64"
compressedBase64 = compress.CompressStringENC(sb.GetAsString())
print("Compressed Bytes as Base64: " + compressedBase64)

# Now decompress...

# To decompress from Base64...
