这就是我刚刚使用和工作的内容。@arne的答案已针对Python 3更新，还包括复制变量属性：
import netCDF4 as nc
toexclude = ['ExcludeVar1', 'ExcludeVar2']
with netCDF4.Dataset("in.nc") as src, netCDF4.Dataset("out.nc", "w") as dst:
# copy global attributes all at once via dictionary
dst.setncatts(src.__dict__)
# copy dimensions
for name, dimension in src.dimensions.items():
dst.createDimension(
name, (len(dimension) if not dimension.isunlimited() else None))
# copy all file data except for the excluded
for name, variable in src.variables.items():
if name not in toexclude:
x = dst.createVariable(name, variable.datatype, variable.dimensions)
dst[name][:] = src[name][:]
# copy variable attributes all at once via dictionary
dst[name].setncatts(src[name].__dict__)
