(CkPython) Unzip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to unzip only those files with a last-modified date within a date range.

Note: This example requires Chilkat v10.0.0 or greater.

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

zip = chilkat.CkZip()

success = zip.OpenZip("qa_data/zips/sample.zip")
if (success != True):
    print(zip.lastErrorText())
    sys.exit()

# The MinDate and MaxDate properties use the timestamp date/time string format.
# Here are some examples:
# YYYY-MM-DD (e.g., 2024-07-31)
# YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)
# 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC)

# Only unzip files having a last-modified date greater than 1-Jan-2017
zip.put_MinDate("2017-01-01T00:00:00Z")

# Also, only unzip files having a last-modified date less than the end of 2020
zip.put_MaxDate("2020-12-31T23:59:59Z")

# You don't need to specify both MinDate and MaxDate.
# You can specify only one or the other if needed.

# The MinDate/MaxDate properties apply to all of the Chilkat methods for unzipping.
