ee.String.slice

  • String.slice() extracts a portion of a string, returning a new string.

  • It uses start and end indices to define the substring, with start being inclusive and end exclusive.

  • Negative indices are supported, counting backwards from the string's end.

  • If the specified range goes beyond the string's boundaries, a shorter substring within those boundaries is returned.

  • It's applicable in both JavaScript and Python environments within the Earth Engine context.

 Returns a substring of the given string. If the specified range exceeds the length of the string, returns a shorter substring.

UsageReturns
String.slice(start, end)String
ArgumentTypeDetails
this: stringStringThe string to subset.
startIntegerThe beginning index, inclusive. Negative numbers count backwards from the end of the string.
endInteger, default: nullThe ending index, exclusive. Defaults to the length of the string. Negative numbers count backwards from the end of the string.

Examples

Code Editor (JavaScript)

print(ee.String('').slice(0));  // ''
print(ee.String('').slice(-1));  // ''

var s = ee.String('abcdefghijklmnopqrstuvwxyz');
print(s.slice(0));  // abcdefghijklmnopqrstuvwxyz
print(s.slice(24));  // yz
print(s.slice(-3));  // xyz
print(s.slice(3, 3));  // ''
print(s.slice(2, 3));  // c
print(s.slice(-4, 25)); // wxy

Python setup

See the Python Environment page for information on the Python API and using geemap for interactive development.

import ee
import geemap.core as geemap

Colab (Python)

print(ee.String('').slice(0).getInfo())  # ''
print(ee.String('').slice(-1).getInfo())  # ''

s = ee.String('abcdefghijklmnopqrstuvwxyz')
print(s.slice(0).getInfo())  # abcdefghijklmnopqrstuvwxyz
print(s.slice(24).getInfo())  # yz
print(s.slice(-3).getInfo())  # xyz
print(s.slice(3, 3).getInfo())  # ''
print(s.slice(2, 3).getInfo())  # c
print(s.slice(-4, 25).getInfo())  # wxy
